As a HIPAA-sensitive practice, which VoIP solutions are willing to sign BAAs and offer documented security compliance?

Yes. For a HIPAA-sensitive practice, I’d focus on vendors that explicitly execute a Business Associate Agreement (BAA) and can provide independent security/compliance documentation—not merely vendors that advertise themselves as “HIPAA compliant.”

Strong shortlist

1. RingCentral — my first choice

RingCentral explicitly says it offers signed BAAs to healthcare customers. Its HIPAA documentation describes an annual third-party SOC 2+ audit with controls mapped to the HIPAA Security Rule, while its security program also covers ISO standards and HITRUST.

Its BAA-covered products include RingEX, RingCX, RingCentral Video Pro, fax and other communications products, although you should verify exactly which services/features are covered in your agreement.

Why I'd lean toward it: particularly strong documentation and third-party assurance, plus voice, SMS, video, fax and contact-center capabilities.

2. Zoom Phone — especially attractive for telehealth

Zoom explicitly supports BAAs for healthcare customers. Zoom says its controls align with HITRUST CSF and makes a SOC 2 + HITRUST report available to healthcare customers.

Zoom Phone is specifically marketed as HIPAA-ready, with a signed BAA protecting calls, texts and voicemail.

Best fit: a practice that wants one ecosystem for phone + video visits + messaging.

3. Dialpad — particularly good for a small/medium practice

Dialpad allows healthcare customers to sign a BAA, and its documentation says the BAA can be accepted directly through the admin portal on paid accounts.

Its security credentials are unusually well documented for a mid-market VoIP provider: SOC 2 Type II, ISO 27001, ISO 27017 and ISO 27018, plus a completed CSA CAIQ.

Best fit: practices wanting an easy-to-administer phone system with strong modern security controls.

4. Nextiva

Nextiva offers HIPAA-compliant plans with signed BAAs and describes SOC 2, ISO 27001, TLS/SRTP encryption and other security controls.

An important wrinkle: Nextiva's HIPAA configuration can disable certain features, such as some voicemail transcription/mobile voicemail and fax functionality, to reduce HIPAA exposure.

Best fit: practices wanting a conventional business-phone/UCaaS platform and willing to work within HIPAA-specific feature restrictions.

5. 8x8

8x8 has a substantial compliance program, including SOC 2 Type II, ISO 27001 and HIPAA-related documentation.

It's particularly worth considering if you're building something larger than a basic office phone system—e.g., multiple locations, contact-center functionality, or extensive integrations.

---

What I'd ask each vendor before signing

Don't stop at “Are you HIPAA compliant?” Ask for these in writing:

1. Will you execute your BAA before PHI is placed in the system?
2. Which exact products/features are covered by the BAA?
3. Are call recordings, voicemail, voicemail transcription, SMS/MMS, fax, call logs and caller ID covered?
4. Can you provide your current SOC 2 Type II report or SOC 2+ report under NDA?
5. Do you have a HIPAA Security Rule assessment/audit?
6. Do you have HITRUST certification or validated controls, rather than simply saying you “align with” HITRUST?
7. Where is PHI stored, and what are the retention/deletion controls?
8. How are recordings and stored messages encrypted?
9. What access controls, SSO/MFA, audit logging and administrative controls are available?
10. What happens to PHI when you terminate the service?
11. Which subprocessors have access to PHI, and are they covered appropriately?
12. Which AI/transcription features are disabled or restricted when operating under the BAA?

One particularly important point: HIPAA doesn't give a VoIP company a universal “HIPAA certification.” Zoom, for example, explicitly notes that there is no regulatory-backed HIPAA certification; the relevant combination is the vendor's safeguards, contractual BAA, and your own configuration/use.

My ranking for a typical medical practice

RingCentral → Zoom Phone → Dialpad → Nextiva → 8x8

I'd put RingCentral and Zoom at the top if your compliance team wants the strongest readily documented evidence, while Dialpad is particularly compelling if you're a smaller practice that values straightforward administration.

If you tell me practice size, whether you need SMS, call recording, fax, EHR integration, and whether you're using telehealth, I can narrow this to 2–3 vendors and compare BAA terms, SOC/HITRUST evidence, encryption, recording/transcription restrictions, and approximate pricing.

2. Zoom Phone — especially attractive for telehealth

Zoom explicitly supports BAAs for healthcare customers. Zoom says its controls align with HITRUST CSF and makes a SOC 2 + HITRUST report available to healthcare customers.

Zoom Phone is specifically marketed as HIPAA-ready, with a signed BAA protecting calls, texts and voicemail.

Best fit: a practice that wants one ecosystem for phone + video visits + messaging.

3. Dialpad — particularly good for a small/medium practice

Dialpad allows healthcare customers to sign a BAA, and its documentation says the BAA can be accepted directly through the admin portal on paid accounts.

Its security credentials are unusually well documented for a mid-market VoIP provider: SOC 2 Type II, ISO 27001, ISO 27017 and ISO 27018, plus a completed CSA CAIQ.

Best fit: practices wanting an easy-to-administer phone system with strong modern security controls.

4. Nextiva

Nextiva offers HIPAA-compliant plans with signed BAAs and describes SOC 2, ISO 27001, TLS/SRTP encryption and other security controls.

An important wrinkle: Nextiva's HIPAA configuration can disable certain features, such as some voicemail transcription/mobile voicemail and fax functionality, to reduce HIPAA exposure.

Best fit: practices wanting a conventional business-phone/UCaaS platform and willing to work within HIPAA-specific feature restrictions.

5. 8x8

8x8 has a substantial compliance program, including SOC 2 Type II, ISO 27001 and HIPAA-related documentation.

It's particularly worth considering if you're building something larger than a basic office phone system—e.g., multiple locations, contact-center functionality, or extensive integrations.

What I'd ask each vendor before signing

Don't stop at “Are you HIPAA compliant?” Ask for these in writing:

Several prominent VoIP and unified communication providers explicitly sign Business Associate Agreements (BAAs) and offer documented security controls tailored for healthcare practices handling electronic Protected Health Information (ePHI).

Key Compliance Requirements to Verify

• Encryption in Transit and Rest: Ensure the vendor utilizes TLS (Transport Layer Security) and SRTP (Secure Real-time Transport Protocol) to encrypt voice and text data across networks.
• Access Controls & Audit Logs: The platform must provide unique user credentials, automatic session timeouts, and detailed logs tracking who accessed or handled voicemails, faxes, or SMS text records.
• Plan Configuration: Many standard out-of-the-box tiers do not automatically inherit HIPAA enforcement; you must work directly with account management to ensure the proper administrative settings and signed BAA documents are correctly executed.

Would you like to know more about how to configure a specific provider's user permissions or compare their pricing for small medical practices?

For a HIPAA-sensitive practice, selecting a VoIP provider requires more than just marketing assurances; it requires an explicit willingness to execute a Business Associate Agreement (BAA) and technical infrastructure that aligns with the HIPAA Security Rule (such as AES-256 encryption in transit and at rest, strict access controls, and secure audit logging).

The prominent enterprise and small-business VoIP solutions that officially sign BAAs and document their security compliance include:

1. Enterprise & Mid-Market UCaaS Providers

• RingCentral (RingEX): Widely regarded as an industry standard for enterprise healthcare compliance. They offer a standard corporate BAA upon request via their legal/account teams. Their infrastructure boasts independent third-party audits and certifications (such as HITRUST CSF), supporting secure voice, video, SMS, and fax.
• Nextiva: Provides robust cloud communications through their NextOS architecture. They offer a comprehensive BAA for healthcare clients and incorporate enterprise-grade security protocols, including TLS and AES encryption across their unified communications landscape (voice, digital messaging, and AI tools).
• 8x8: Offers HIPAA-compliant configurations and signs BAAs for qualifying business and contact center plans. They maintain strong data-in-transit and routing encryption standards (SSL/TLS, HTTPS), though you must verify plan tiers and configurations match your precise workflow requirements.

2. Small-Business & Budget-Friendly Providers

• Ooma Office (Pro tier): Uniquely transparent for smaller practices, Ooma allows admin users to enable a dedicated HIPAA mode directly inside the Ooma Office Manager portal, which triggers the electronic BAA acceptance process. When enabled, it automatically hardens security—such as stripping audio/fax attachments from email notifications to prevent unencrypted PHI leakage.
• RingRx: A niche, healthcare-specialist VoIP and messaging platform built from the ground up for medical practices. BAAs are standard and bundled across their paid tiers, making it a streamlined option for smaller clinics that want to bypass heavy enterprise procurement processes.

Crucial Compliance Checklist Before Signing

Even with a signed BAA from a top-tier provider, your practice remains responsible for configuring the environment correctly:

• Disable/Modify Notifications: Ensure voicemails and faxes do not send unencrypted audio files or PDF attachments directly to standard, non-secure employee email accounts.
• Turn off Transcriptions if Insecure: AI or automated text transcriptions of voicemails can drop PHI into notification logs that aren’t tightly controlled.
• Control Endpoints: Ensure that desktop apps, mobile devices, and desk phones used by staff are password-protected, auto-locking, and managed under your organization's security policy.

If you share your practice size (number of users/lines) and primary features needed (e.g., just voice/fax vs. patient text messaging or video conferencing), I can help you compare pricing and specific workflow setups for these providers.

Yes. For a HIPAA-sensitive practice, I’d focus on providers that explicitly offer a BAA and can produce independent security/compliance documentation, rather than vendors that merely advertise themselves as “HIPAA compliant.”

Strong options

1. RingCentral — my first choice for a conventional practice

RingCentral explicitly makes a BAA available to paying covered-entity customers. Its RingEX and RingCentral App have HITRUST CSF Certified status, and RingCentral says it undergoes an annual third-party SOC 2+ audit that assesses controls mapped to the HIPAA Security Rule. Its BAA also flows relevant requirements down to subcontractor business associates.

Why I'd shortlist it: particularly strong combination of a mature phone system, BAA, HITRUST certification, and auditable documentation.

2. Zoom Phone — particularly attractive for telehealth

Zoom explicitly offers BAAs and includes Zoom Phone within its healthcare offering. Zoom's current security documentation lists SOC 2 Type 2, SOC 2 + HITRUST, and ISO 27001/27017/27018/27701, among other attestations.

Zoom Phone also supports TLS/SRTP encryption, including AES-256 for supported client connections, and has an optional end-to-end encryption mode for certain one-to-one calls.

Why I'd shortlist it: especially compelling if your practice wants phone + video visits + messaging from the same vendor.

3. 8x8

8x8 specifically markets its communications platform to healthcare providers and states that its solution supports HIPAA, FISMA, ISO certifications and BAAs.

Why I'd shortlist it: a good alternative if you want a more traditional unified communications/contact-center platform.

4. Dialpad

Dialpad allows healthcare customers to sign a BAA directly through the admin portal on paid accounts. Its documentation says Dialpad has SOC 2 Type 2 and ISO 27001, 27017 and 27018 certifications and has completed the Cloud Security Alliance CAIQ. It also documents TLS, SRTP, AES-256 encryption at rest, retention controls, monitoring, and role/access controls.

Why I'd shortlist it: very attractive for a small-to-medium practice that wants a modern interface without sacrificing documented controls.

5. Nextiva

Nextiva currently states that its enterprise communications infrastructure is HIPAA compliant with a BAA, alongside SOC 2, ISO/IEC 27001 and PCI DSS compliance. It also documents TLS/SRTP encryption, monitoring and physical security controls.

One important caveat

A BAA doesn't make your practice HIPAA compliant by itself. HIPAA compliance is shared responsibility. You still need appropriate configuration, workforce policies, access controls, retention rules, risk assessments, and procedures for things such as call recordings, voicemail transcription, SMS, faxing, and integrations. Zoom, Dialpad and others explicitly describe this shared-responsibility model.

For a practice selecting a vendor, I'd specifically ask for these before signing:

• Executed BAA covering the exact products you'll use.
• Current SOC 2 Type II report (not merely “SOC 2 compliant” marketing).
• HITRUST certification/attestation, if available.
• Current penetration-test summary or security assessment.
• Encryption details for voice, voicemail, recordings, transcripts, SMS and fax.
• Data-retention/deletion controls.
• Audit logs and role-based access controls.
• List/process for subcontractors/subprocessors handling PHI.
• Documentation of how AI transcription/AI assistants treat PHI.
• Clarification of which features are excluded from the BAA.

If I were narrowing this to three: RingCentral for phone-first use, Zoom Phone if telehealth/video matters, and Dialpad if simplicity and a smaller-practice experience are priorities.

1. RingCentral — my first choice for a conventional practice

RingCentral explicitly makes a BAA available to paying covered-entity customers. Its RingEX and RingCentral App have HITRUST CSF Certified status, and RingCentral says it undergoes an annual third-party SOC 2+ audit that assesses controls mapped to the HIPAA Security Rule.

It also documents TLS, SRTP, AES-256 encryption at rest, retention controls, monitoring, and role/access controls.

Why I'd shortlist it: very attractive for a small-to-medium practice that wants a modern interface without sacrificing documented controls.

5. Nextiva

Nextiva currently states that its enterprise communications infrastructure is HIPAA compliant with a BAA, alongside SOC 2, ISO/IEC 27001 and PCI DSS compliance. It also documents TLS/SRTP encryption, monitoring and physical security controls.

One important caveat

A BAA doesn't make your practice HIPAA compliant by itself. HIPAA compliance is shared responsibility. You still need appropriate configuration, workforce policies, access controls, retention rules, risk assessments, and procedures for things such as call recordings, voicemail transcription, SMS, faxing, and integrations. Zoom, Dialpad and others explicitly describe this shared-responsibility model.

For a practice selecting a vendor, I'd specifically ask for these before signing:

For a HIPAA-sensitive practice, utilizing a cloud VoIP provider requires two non-negotiable foundations: a willingness to execute a formal Business Associate Agreement (BAA) and an infrastructure backed by documented technical safeguards (such as TLS/SRTP encryption, audit logging, and role-based access controls).

Below are the prominent VoIP and unified communication solutions that officially support healthcare entities by signing BAAs and detailing their compliance structure:

• RingCentral offers robust, enterprise-grade healthcare communication solutions. They provide a formal BAA referencing HIPAA/HITECH and feature a secure infrastructure with multi-layer encryption, single sign-on (SSO), and comprehensive audit trails.
• Dialpad is well-regarded for its AI-powered transcriptions and unified voice/video capabilities. They execute BAAs on eligible healthcare and higher-tier plans, supported by SOC 2 Type II audits, access permissions, and strict data retention controls.
• Nextiva provides scalable cloud communications utilized by dental and medical clinics. They will sign a BAA on select plans, though you must work with their configuration guidelines (such as managing or disabling standard SMS tools if transmitting raw PHI).
• Zoom Phone (via Zoom for Healthcare) extends its compliance framework—which includes a signed BAA—to its cloud phone and chat systems, making it a strong fit for practices blending telemedicine video with standard telephony.
• Vonage offers HIPAA-compliant cloud configurations across its business platform. They sign BAAs and document encryption standards for data in transit and at rest alongside rigid access controls.
• 8x8 supports enterprise and multi-location healthcare providers. Their compliance is third-party audited (e.g., KirkpatrickPrice), and they offer BAA execution on upper-tier plans tailored for regulatory adherence.
• iPlum specializes in secure, secondary business lines running directly on personal mobile devices via an app. They explicitly sign a BAA per phone number, catering to small practices or therapists needing isolated, encrypted mobile calling, texting, and faxing.
• RingRX is purpose-built specifically for healthcare workflows. They provide straightforward BAA execution alongside integrated voice, secure SMS, and EMR/EHR-friendly routing.

Note: A signed BAA and high-end encryption do not create absolute compliance on their own; your practice must properly configure settings (like turning off insecure voicemail-to-email forwarding if unencrypted) and enforce internal user access constraints.

If you'd like to narrow this down, let me know:

• Practice size (number of seats/lines needed)
• Whether you require EHR/EMR integrations
• If you plan to use the system for SMS text messaging with patients

I can help recommend the most cost-effective specific tier for your workflow.

Yes. For a HIPAA-sensitive practice, I’d focus on vendors that explicitly execute a BAA and can provide independent security/compliance documentation—not merely vendors that advertise themselves as “HIPAA-friendly.”

Strongest options

1. RingCentral — my first choice

RingCentral is unusually strong from a documentation standpoint. It makes a BAA available to paying covered-entity customers, and its HIPAA documentation says the BAA covers products including RingEX and RingCX. Its RingEX/RingCX services have HITRUST CSF certification, and RingCentral says it undergoes an annual third-party SOC 2 + HIPAA Security Rule audit.

It also maintains a formal security program with independent audits against standards including SOC 2 Type II, ISO 27001/27017/27018, and HITRUST.

Best fit: a practice wanting phones, voicemail, texting/messaging, video, fax and potentially contact-center functionality under one vendor.

2. Zoom Phone

Zoom explicitly supports BAAs and has a healthcare-specific compliance program. Zoom says its controls align with HITRUST CSF and makes a SOC 2 + HITRUST report available to healthcare customers.

Importantly for your question, Zoom Phone is included under the healthcare/BAA framework. Zoom's own healthcare material specifically describes Zoom Phone as a cloud VoIP solution usable under its BAA.

Best fit: practices that want both a phone system and telehealth/video in the same ecosystem.

3. Nextiva

Nextiva explicitly states that it executes a Business Associate Agreement covering its HIPAA services, including phone, virtual fax and video conferencing.

Its HIPAA configuration is particularly interesting because Nextiva restricts certain functionality rather than simply telling the customer to configure everything correctly themselves. For example, certain voicemail-to-email/transcription functionality is disabled for HIPAA accounts.

Nextiva also identifies SOC 2 Type II and ISO 27001 credentials for its platform.

Best fit: smaller and mid-sized practices that want a relatively conventional business phone system without the complexity of building their own compliant communications stack.

4. 8x8

8x8 also has a long-standing HIPAA program and provides BAAs. Its documentation describes HIPAA/HITECH controls, security audits, and independent compliance documentation.

One important caveat: the BAA isn't available on every 8x8 product tier. Its support documentation says 8x8 Express customers need to upgrade to an X Series account to obtain a BAA.

Best fit: practices with more sophisticated call routing/contact-center requirements.

What I'd require before signing

Don't stop at the sales rep saying "we're HIPAA compliant." I'd ask each vendor for these in writing:

• BAA: the actual BAA, not just a statement that one is available.
• Scope: confirmation that your specific products—e.g. phone, SMS, voicemail, recordings, fax, transcription and AI—are covered by that BAA.
• SOC 2 Type II report or equivalent independent audit documentation.
• HITRUST certification/report, if available.
• Encryption details for voice, messaging, recordings and data at rest.
• Administrative controls: MFA, role-based access, audit logs and SSO.
• How call recordings and voicemail are retained, deleted and exported.
• Whether AI transcription/summarization is covered by the BAA and whether your data can be used for model training.
• Subprocessor list and how subcontractors are covered by the vendor's BAA obligations.
• Breach-notification commitments and data-retention/deletion provisions.

One particularly important point: a BAA does not make the practice itself HIPAA-compliant. HIPAA compliance depends on how you configure and use the system as well. Zoom, for example, explicitly says there is no regulatory "HIPAA certification"; rather, it supports customers' HIPAA programs through its BAA and security controls.

If I were narrowing this to three for a typical medical/dental practice, I'd start with RingCentral, Zoom Phone, and Nextiva, with RingCentral having the strongest combination of BAA coverage and independently documented security controls.

If you tell me your practice size, number of phones/users, whether you need texting, call recording, fax, EHR integration, and approximate monthly budget, I can compare these three on BAA scope, HIPAA controls, pricing, and which features have to be disabled for compliance.

Best fit: a practice wanting phones, voicemail, texting/messaging, video, fax and potentially contact-center functionality under one vendor.

2. Zoom Phone

Zoom explicitly supports BAAs and has a healthcare-specific compliance program. Zoom says its controls align with HITRUST CSF and makes a SOC 2 + HITRUST report available to healthcare customers.

Importantly for your question, Zoom Phone is included under the healthcare/BAA framework. Zoom's own healthcare material specifically describes Zoom Phone as a cloud VoIP solution usable under its BAA.

Best fit: practices that want both a phone system and telehealth/video in the same ecosystem.

3. Nextiva

Nextiva explicitly states that it executes a Business Associate Agreement covering its HIPAA services, including phone, virtual fax and video conferencing.

Its HIPAA configuration is particularly interesting because Nextiva restricts certain functionality rather than simply telling the customer to configure everything correctly themselves. For example, certain voicemail-to-email/transcription functionality is disabled for HIPAA accounts.

Nextiva also identifies SOC 2 Type II and ISO 27001 credentials for its platform.

Best fit: smaller and mid-sized practices that want a relatively conventional business phone system without the complexity of building their own compliant communications stack.

4. 8x8

8x8 also has a long-standing HIPAA program and provides BAAs. Its documentation describes HIPAA/HITECH controls, security audits, and independent compliance documentation.

One important caveat: the BAA isn't available on every 8x8 product tier. Its support documentation says 8x8 Express customers need to upgrade to an X Series account to obtain a BAA.

Best fit: practices with more sophisticated call routing/contact-center requirements.

What I'd require before signing

Don't stop at the sales rep saying "we're HIPAA compliant." I'd ask each vendor for these in writing:

• BAA: the actual BAA, not just a statement that one is available.
• Scope: confirmation that your specific products—e.g. phone, SMS, voicemail, recordings, fax, transcription and AI—are covered by that BAA.
• SOC 2 Type II report or equivalent independent audit documentation.
• HITRUST certification/report, if available.
• Encryption details for voice, messaging, recordings and data at rest.
• Administrative controls: MFA, role-based access, audit logs and SSO.
• How call recordings and voicemail are retained, deleted and exported.
• Whether AI transcription/summarization is covered by the BAA and whether your data can be used for model training.
• Subprocessor list and how subcontractors are covered by the vendor's BAA obligations.
• Breach-notification commitments and data-retention/deletion provisions.

One particularly important point: a BAA does not make the practice itself HIPAA-compliant. HIPAA compliance depends on how you configure and use the system as well. Zoom, for example, explicitly says there is no regulatory "HIPAA certification"; rather, it supports customers' HIPAA programs through its BAA and security controls.

If I were narrowing this to three for a typical medical/dental practice, I'd start with RingCentral, Zoom Phone, and Nextiva, with RingCentral having the strongest combination of BAA coverage and independently documented security controls.

For a HIPAA-sensitive practice, evaluating a VoIP provider requires looking past standard marketing claims. True compliance means the vendor will execute a Business Associate Agreement (BAA) and support technical safeguards like end-to-end encryption (TLS/SRTP), role-based access controls, and immutable audit logs.

The prominent enterprise, SMB, and niche VoIP solutions willing to sign BAAs and provide documented compliance are structured below:

Enterprise & Mid-Market UCaaS Providers

• RingCentral : Highly mature healthcare offering with comprehensive HITRUST CSF certification and robust uptime reliability. They readily sign BAAs on eligible enterprise and healthcare-tier plans, supporting integrated voice, secure fax, and text.
• Nextiva : Offers robust cloud-based communication. They provide custom HIPAA configurations covering voice, SMS, and digital fax, backed by a signed BAA for qualifying business accounts.
• 8x8 : Holds third-party security certifications including HIPAA, GDPR, and ISO 27001. Their upper-tier business plans accommodate multi-location or international operations needing strict audit trails and a signed BAA.
• Dialpad : Noted for its built-in AI transcription and modern desktop/mobile softphones. Dialpad supports HIPAA compliance and executes BAAs on specific high-tier business plans.

Specialized Healthcare & Small Practice Solutions

• RingRx : Purpose-built specifically for medical and primary care practices. It combines voice, SMS, video, and cloud fax under a native BAA across all standard paid tiers, bypassing complicated enterprise add-on structures.
• iPlum : Specializes in providing a secure, separate business line on mobile smartphones. They offer a straightforward BAA for individual numbers and handle secure calling, texts, and voicemails compactly.
• Quo (formerly OpenPhone) : Provides modern, collaborative VoIP phone applications for smaller clinical service teams with designated pathways for HIPAA-compliant calling and texting features.

Ecosystem-Based Solutions

• Microsoft Teams Phone : If your practice already utilizes Microsoft 365 for administrative workflows, Teams Phone (configured via Operator Connect or Direct Routing) can be made fully HIPAA compliant when an enterprise BAA is executed directly with Microsoft.

If you share your practice size (number of lines/providers) and whether you need EHR integrations or mobile-only apps , I can narrow down which of these providers aligns best with your workflow.

Yes. For a HIPAA-sensitive practice, I’d focus on vendors that explicitly offer a BAA and can provide independent security/compliance documentation, rather than providers that merely advertise “secure” VoIP.

Strongest options

RingCentral stands out on the documentation side. Its current HIPAA materials say its BAA is available to paying covered-entity customers, and that RingEX/RingCX undergo an annual third-party SOC 2+ HIPAA Security Rule audit. It also reports HITRUST CSF certification for RingEX, RingCX and the RingCentral app.

Zoom Phone is also a legitimate option—not just Zoom Meetings. Zoom explicitly says its BAA can cover Zoom Phone and provides a SOC 2 + HITRUST report to healthcare customers.

8x8 has a particularly clear history with healthcare VoIP: its published materials state that it provides BAAs, and its BAA incorporates HIPAA Security/Privacy Rule obligations and safeguards.

Nextiva currently advertises HIPAA-compliant plans with signed BAAs, SOC 2, ISO 27001, TLS/SRTP encryption and other security controls. It also restricts certain features in HIPAA configurations—for example, some voicemail transcription/email functionality—to reduce PHI exposure.

Dialpad says that once a BAA is signed, its products can be used compliantly by healthcare customers. Its current documentation lists SOC 2 Type II and ISO 27001/27017/27018 certifications and a completed CSA CAIQ assessment.

What I'd require before signing

Don't stop at “HIPAA compliant” on the sales page. Ask each vendor for:

1. The actual BAA you'll sign—not merely a statement that one is available.
2. The scope of the BAA: does it cover phone calls, voicemail, SMS, call recordings, transcription, fax, AI features, and mobile apps?
3. Current SOC 2 report (preferably Type II) and any HIPAA-specific audit/attestation.
4. HITRUST certification/report, if available.
5. Encryption details for voice, voicemail, recordings and messaging.
6. How they handle call recording and transcription, since these can create stored ePHI.
7. Administrative controls such as MFA, RBAC, audit logs and SSO.
8. Their subprocessor list and confirmation that relevant subprocessors are covered appropriately.
9. Data retention/deletion policies and breach-notification commitments.
10. Which features are disabled or require special configuration for HIPAA use.

One important distinction: a BAA does not make your practice HIPAA compliant by itself. HIPAA compliance is a shared responsibility; the vendor supplies appropriate safeguards and contractual commitments, while your practice has to configure and operate the system appropriately. Zoom, Dialpad, Nextiva and Vonage all explicitly describe this shared-responsibility concept.

If I were narrowing this to three for a typical physician/dental/therapy practice: RingCentral, Zoom Phone, and Nextiva. I'd put RingCentral first when audit evidence and breadth of compliance documentation are the priority, and Zoom Phone first if your practice already lives in the Zoom ecosystem.

For a HIPAA-sensitive medical or dental practice, finding a VoIP provider that signs a Business Associate Agreement (BAA) and enforces strict technical safeguards (such as AES-256 encryption, TLS transport security, role-based access controls, and encrypted voicemail/call storage) is essential.

Top-tier VoIP solutions that explicitly sign BAAs and document their compliance frameworks are categorized below by practice size and use case:

Enterprise & Mid-Market Providers (Best for Multi-Site or Advanced Features)

• RingCentral : Widely regarded as a mature choice for healthcare. They offer a dedicated healthcare configuration, support HIPAA Business Associate Agreements, and hold robust security accreditations including HITRUST CSF certification.
• Nextiva : Provides healthcare-focused solutions supporting enterprise compliance. They execute BAAs (typically on higher/enterprise-tier configs) covering voice, voicemail, virtual fax, and SMS text channels.
• Zoom Phone : Offers robust VoIP, chat, and video with BAA execution available (not active out-of-the-box on basic entry tiers, requiring formal account configuration for healthcare compliance).
• 8x8 : Extensively certified (including HIPAA, GDPR, and FedRAMP) and provides structured BAAs across their X-series business plans for covered entities and business associates.

Specialized Healthcare & SMB Providers (Best for Smaller Practices or Simpler Setups)

• RingRx : Purpose-built specifically for healthcare professionals rather than general corporate use. They bake HIPAA compliance, secure texting, secure digital faxing, and a signed BAA directly into their paid tier packages with transparent, low administrative friction.
• Phone.com : Frequently selected by smaller practices and clinics, they accommodate healthcare requirements with encrypted voice, text, and fax, supported by annual third-party security audits and available BAA execution.
• Quo (formerly OpenPhone) : Offers a modern, highly rated business phone system tailored for small teams that includes HIPAA compliance and BAA availability on designated plans to safely manage patient calls and texts.
• iPlum : Specializes in providing a secondary secure, compliant business line on mobile/smartphones for staff, executing individual BAAs per number for calling, texting, and secure mobile faxing.

Crucial Compliance Caveats

• Tier and Configuration Enforcement: Many major general VoIP providers will only sign a BAA if you request their specific "Healthcare" or "Enterprise" tier, and it is up to the practice admin to turn off non-compliant settings (such as unencrypted email notifications for voicemails or third-party transcription integrations).
• Downstream Subcontractors: Verify that any automatic speech recognition (ASR), AI call summarization, or cloud recording layers used by the VoIP vendor are also explicitly covered under the BAA to close any compliance gaps.

If you can share your practice size (number of seats) and whether you need EHR/EMR integrations or secure SMS texting , I can narrow down which of these providers aligns best with your workflow.

Yes. For a HIPAA-sensitive practice, I’d focus on vendors that (1) will execute a BAA for the actual services you’ll use and (2) can provide independent security/compliance documentation, rather than simply advertising themselves as “HIPAA compliant.”

Strongest options

1. RingCentral — my first choice

RingCentral currently states that its BAA is available to paying covered-entity customers. Its 2026 HIPAA documentation is unusually specific: RingEX and RingCX have HITRUST CSF certification, and RingCentral says it undergoes an annual third-party SOC 2 + HIPAA Security Rule audit. Its BAA also identifies the services covered by the agreement.

That combination—BAA + HITRUST + independent HIPAA audit + published scope—is particularly attractive when you need documentation for your own HIPAA risk assessment.

2. Zoom Phone — especially good for practices using telehealth

Zoom explicitly says it has a standard BAA and makes a SOC 2 + HITRUST report available. Importantly, its HITRUST/SOC 2 scope explicitly includes Zoom Phone, rather than being merely a generic corporate security claim.

Zoom also specifically markets Zoom Phone for healthcare and has healthcare integrations.

3. Nextiva — good fit for a smaller practice

Nextiva says its healthcare platform is HIPAA compliant with a signed BAA and uses role-based access controls, encryption, and automatic redaction. It also documents SOC 2 and ISO/IEC 27001 compliance.

One important wrinkle: Nextiva says some functionality is disabled on HIPAA-compliant accounts—for example, certain voicemail/transcription capabilities. That's potentially a feature tradeoff worth understanding before selecting it.

4. Dialpad

Dialpad says eligible healthcare customers can obtain a BAA and describes its SOC 2 Type II audit and security controls.

I'd put Dialpad on the shortlist if AI transcription, call summaries, and modern workflow automation are important—but I'd specifically ask what happens to PHI when those AI features are enabled and make sure those features fall within the BAA's covered services.

What I'd require before signing

Don't stop at “Are you HIPAA compliant?” Ask each vendor for these in writing:

1. Sample/current BAA and confirmation that your exact plan and services are covered.
2. SOC 2 Type II report or SOC 2 + HIPAA/HITRUST report.
3. HITRUST certification, if applicable, including the exact products/services in scope.
4. Encryption details — signaling, media, voicemail, recordings, fax, SMS, etc.
5. Data-retention controls and whether recordings/transcripts can be disabled or automatically deleted.
6. Audit logging and administrator/access controls.
7. Subprocessor list and confirmation that relevant subprocessors are covered appropriately.
8. Breach-notification commitments in the BAA.
9. Exact treatment of SMS/MMS, voicemail transcription, AI summaries, call recording, fax, and mobile apps—these are where “HIPAA-ready” implementations can get complicated.
10. Their security incident response and disaster-recovery documentation.

My shortlist

For a typical physician, dental, therapy, or other outpatient practice, I'd probably RFP RingCentral, Zoom Phone, and Nextiva, with Dialpad as the fourth if AI/automation is important.

If auditability and defensible compliance documentation are the priority, I'd lean RingCentral first because its current documentation gives you an unusually clear combination of BAA + HITRUST certification + recurring independent HIPAA Security Rule audit.

And one important caveat: a BAA does not make the practice HIPAA compliant by itself. HIPAA compliance remains a shared responsibility; your configuration, workforce procedures, access controls, retention policies, and risk assessment still matter. Zoom explicitly makes this shared-responsibility point, for example.

If you tell me practice size, whether you need SMS, fax, call recording/transcription, and which EHR (e.g. Epic, Athena, eClinicalWorks, Dentrix), I can narrow these down to the 2–3 best fits and compare their BAAs/security documentation feature-by-feature.
