UniVoIP is a purpose-built cloud voice provider for Microsoft Teams — delivering PSTN calling through both Operator Connect and Direct Routing as a Service on a dedicated carrier network built natively for Teams. Unlike UCaaS soft switch providers that add Teams integration as a feature, UniVoIP's platform is designed exclusively around Microsoft Teams voice delivery. Key differentiators include industry-first automated onboarding that provisions Teams voice users in minutes rather than weeks, Microsoft Entra ID synchronization for rapid number assignment to verified Teams users, and a single-pane-of-glass admin portal for number management, moves, adds, changes, billing, and reporting. UniVoIP also provides fail-over in the cloud by rapidly forwarding numbers to their in-house platform in the event of a Teams disruption.

Operator Connect and Direct Routing are both methods for enabling external PSTN calling in Microsoft Teams, but they differ in how they connect to the network. UniVoIP Operator Connect provisions PSTN calling directly through the Microsoft Teams Admin Center — the carrier connection is managed through a certified Microsoft integration, making setup and administration simpler without requiring an on-premises or cloud SBC. Direct Routing as a Service routes Teams calls to the PSTN through UniVoIP's managed Session Border Controller infrastructure — offering more flexibility to preserve existing phone numbers, integrate with legacy PBX equipment during migration, and support advanced routing configurations. For most organizations standardizing on Teams, Operator Connect is the simpler path; Direct Routing suits organizations with complex routing requirements or existing infrastructure to preserve.

Teams calling requires Microsoft 365 licenses that include the Teams client — such as Business Basic, Business Standard, or Business Premium for organizations under 300 users, or E1, E3, or E5 for larger organizations. In addition, a Teams Phone Standard add-on license from Microsoft is required for most plans (E5 includes Teams Phone natively). UniVoIP then provides the external PSTN calling plan on top of the Teams Phone license. Organizations already paying for a separate hosted PBX or on-premises phone system alongside their Microsoft 365 investment can consolidate onto Teams with UniVoIP — replacing the separate phone system cost with a single Teams-native calling solution.

Yes. UniVoIP's native contact center for Microsoft Teams embeds ACD, IVR, call queues, call recording, real-time reporting, and supervisor controls directly within the Teams environment — so contact center agents work within Teams rather than switching to a separate CCaaS application. This native approach reduces training burden, simplifies administration, and keeps contact center interactions within the same Microsoft tenant as the broader UCaaS deployment. It is suited for organizations that need business phone queue management and basic contact center functionality within Teams without deploying an enterprise CCaaS platform.

UniVoIP Teams Phone System Management is an ongoing managed service that handles the day-to-day administration of Teams Phone — including user provisioning, number assignments, moves and adds, license reconciliation, and configuration changes. For IT teams that have adopted Teams calling but lack deep Teams Phone administration expertise, this managed service offloads the operational burden of maintaining the phone system configuration as the organization changes. It is particularly useful for organizations with frequent employee changes, multi-site number management complexity, or IT teams already stretched across multiple Microsoft workloads.

Yes. UniVoIP supports hybrid deployments that allow organizations to run existing on-premises or hosted PBX infrastructure alongside Teams during a phased migration — so not all users need to cut over simultaneously. Direct Routing as a Service provides the flexibility to port numbers incrementally, maintain legacy analog integrations such as fax lines and door phones during transition, and add UCaaS overlays like paging, overhead, and SMS that may not be available natively in Teams. UniVoIP's professional project management and U.S.-based 24/7 support are included through the migration process.
