Key Takeaways

  • Healthcare is the largest UCaaS industry vertical in Zion Market Research’s current analysis, making HIPAA controls and clinical workflow support central evaluation criteria.
  • HL7 Fast Healthcare Interoperability Resources (FHIR) APIs can connect voice, video, messaging, and contact center as a service (CCaaS) workflows to electronic health record (EHR) data while reducing manual patient-data entry.
  • Buyers should test at least five operational measures: call completion, transfer latency, abandoned-call rate, video quality, and failed EHR context transfers.
  • Crexendo, Inc. and other shortlisted providers should be evaluated against the same security, interoperability, failover, and clinical-workflow requirements.

Define Healthcare Communication Requirements Before Comparing Vendors

A nurse trying to reach an on-call specialist should not have to check a paper roster, leave a voicemail, send a separate text, and then document the exchange manually in the EHR. Yet fragmented workflows like this remain common when desk phones, mobile messaging, telehealth, contact centers, and clinical systems operate independently.

Adoption is already broad. Recent survey data indicates that 82% of healthcare organizations now use unified communications tools to connect with patients and providers, up from 65% in 2021. According to Zion Market Research, the global UCaaS market was valued at about $87.4 billion in 2024 and is projected to reach $519 billion by 2034, with healthcare identified as the largest industry vertical due to its need for efficient provider communication and improved patient care.

The buyer’s first task is therefore not choosing a phone platform. It is documenting communication paths, including patient scheduling calls, nurse escalation, interpreter access, referral coordination, prescription questions, contact-center queues, and telehealth visits.

For each workflow, teams should record the originating system, destination, authentication method, data exchanged, and fallback process. A referral call might originate in a CCaaS queue, retrieve patient context through an HL7 FHIR API, transfer to a specialty clinic using Session Initiation Protocol (SIP), and write the interaction disposition back to the EHR. Buyers unfamiliar with these service categories should first compare baseline UCaaS and CCaaS capabilities.

Build a Healthcare UCaaS Evaluation Scorecard

Vendor demonstrations often focus on calling, meetings, presence, and messaging. Healthcare buyers need to go further by asking vendors to execute realistic workflows in a test environment containing synthetic rather than identifiable patient data.

The evaluation should cover HIPAA business associate agreements, role-based access control, multifactor authentication, encryption in transit and at rest, audit-log retention, emergency calling, number portability, and mobile-device controls. Under the HIPAA privacy and security rules, buyers should determine which vendors and subcontractors create, receive, maintain, or transmit protected health information. Voicemail transcription, meeting recordings, SMS archives, and contact-center transcripts may all contain such information.

Platforms from RingCentral, Vodafone Business, NICE, and Crexendo, Inc. illustrate the range of UCaaS and CCaaS options available. The useful distinction is not the raw feature count. It is whether the selected service can map identities from Microsoft Entra ID or another directory, enforce least-privilege access, support SIP interoperability, and pass contextual data into Epic, Oracle Health, or another EHR through supported APIs.

According to Mordor Intelligence, healthcare and life sciences are the fastest-growing UCaaS vertical, with a projected 27.86% CAGR through 2031 as providers integrate HIPAA-compliant video and cloud collaboration into patient portals and care teams. This reinforces the need to evaluate integration quality rather than rely on a generic checklist of calling features.

Review UCaaS Architecture and HIPAA Boundaries

A healthcare UCaaS architecture commonly includes cloud call control, SIP trunks or session border controllers, Web Real-Time Communication (WebRTC) video, mobile applications, a CCaaS layer, identity management, and EHR integration. Buyers should diagram where protected health information enters that architecture, where it is stored, which parties can access it, and when it is deleted.

HL7 FHIR is a standards-based framework for exchanging clinical data across communication and EHR systems. It can provide patient, appointment, practitioner, and encounter data, but an integration should request only the fields required for the workflow. A scheduling agent may need a patient’s name, appointment status, and clinic location but not the patient’s full medication history.

Call recording deserves particular scrutiny. The platform should support configurable recording by queue, pause-and-resume controls, retention policies, and export to an approved archive. Audit events should identify who accessed a recording, when it was downloaded, and whether it was shared.

A technically capable platform can still fail an operational test. If a broadband outage disables an outpatient clinic, local survivability, mobile failover, or public switched telephone network (PSTN) rerouting may matter more than an analytics dashboard. These controls should also align with the organization’s broader healthcare business-continuity plan.

Plan a Phased Healthcare UCaaS Rollout

Implementation typically starts with discovery and dependency mapping, followed by configuration, a limited pilot, staged migration, and operational handoff. The project team generally includes unified communications engineers, network administrators, EHR integration specialists, security and privacy staff, contact-center leaders, clinical operations representatives, and service-desk personnel.

During discovery, the team should inventory direct inward dial numbers, fax lines, overhead paging, analog devices, emergency endpoints, call queues, and carrier contracts. Fax is a useful tangent because it often exposes hidden dependencies: a cloud voice migration can appear complete while referral departments still rely on analog adapters or a separate electronic-fax gateway.

The pilot should test packet loss, jitter, latency, Wi-Fi roaming, SIP normalization, and EHR context transfer. Shortlisted providers should be asked to demonstrate failed-call routing, identity deprovisioning, audit-log export, and recovery from a simulated wide-area network interruption.

Rather than migrating every facility together, buyers can group sites by clinical risk and technical similarity. Administrative offices may move before emergency departments, while contact-center queues may require parallel routing until disposition codes and customer relationship management or EHR write-backs are validated.

Measure Healthcare UCaaS Performance

The sector-specific UCaaS market in healthcare is projected to grow from $7.88 billion in 2025 to $9.06 billion in 2026, a 14.9% CAGR, according to a Global UCaaS in Healthcare Market Report. However, macro-level growth must translate into local operational improvements. Buyers need localized metrics to determine whether their deployment is improving service.

A practical dashboard can track call completion, abandoned-call rate, median hold time, transfer count, dropped video sessions, failed FHIR transactions, voicemail backlog, and mean time to restore service. Clinical teams can also monitor how often an escalation reaches the correct on-call role without requiring manual directory searches.

The expected result is observable workflow change: fewer duplicate entries, fewer calls transferred between departments, same-session resolution of scheduling questions, and a consistent audit trail across voice, video, and messaging. Specific performance thresholds should be established during the pilot rather than inferred from vendor averages.

Ensuring Operational Resilience

Evaluating communication as part of care delivery rather than as an isolated telephony purchase is critical for long-term success. A SIP call that connects but loses patient context during transfer represents only a partial success.

Identity design also needs early attention. Mapping clinicians, contractors, shared workstations, and contact-center agents after configuration begins can force extensive rework in Microsoft Entra ID groups and role permissions.

Finally, prioritizing downtime testing is essential. A documented rerouting plan, exported emergency contacts, local calling options, and rehearsed service-desk procedures provide more practical resilience than a vendor's uptime percentage viewed on its own. Regional health systems, specialty networks, behavioral health providers, and ambulatory groups can all adapt this approach by scaling the pilot scope while retaining the same strict HIPAA, FHIR, SIP, identity, and failover tests.

How long does a healthcare UCaaS implementation take?

Timing depends on site count, number-porting schedules, EHR interfaces, analog devices, and contact-center complexity. Buyers should plan around discovery, pilot, staged migration, and stabilization phases rather than commit to a fixed duration before SIP inventories and FHIR dependencies are documented.

What is the difference between UCaaS and CCaaS in healthcare?

UCaaS supports workforce calling, video, presence, and messaging, while CCaaS manages patient-facing queues, interactive voice response, workforce management, and agent analytics. Many providers integrate both so an agent can transfer a patient from an interactive voice response queue to a clinical team while preserving call and patient context.

Is UCaaS appropriate for a small healthcare team?

It can be, particularly when a small practice needs secure mobile calling, centralized administration, and telehealth support. The team should still verify the availability and scope of a HIPAA business associate agreement, emergency-calling support, role-based access, and whether EHR integration uses supported HL7 FHIR APIs rather than manual screen scraping.
