    The Complete Guide to Microsoft Teams Phone Integration

    Why Teams Telephony Matters

    Microsoft Teams has become the de facto collaboration platform for businesses worldwide. With over 300 million monthly active users, it's where work happens. But many organisations still struggle with fragmented voice solutions.

    Integration Options

    Direct Routing

    Connect your existing telephony infrastructure to Teams through Session Border Controllers (SBCs). This offers:

    • Maximum flexibility and control
    • Ability to retain existing carrier relationships
    • Support for complex routing requirements

    Operator Connect

    A streamlined approach where certified operators provide PSTN connectivity directly through the Teams admin centre. Benefits include:

    • Simplified management
    • Quick deployment
    • Integrated billing

    Teams Phone with Calling Plans

    Microsoft's all-in-one solution for smaller deployments:

    • No additional infrastructure required
    • Simple per-user licensing
    • Limited geographic availability

    Best Practices for Deployment

    1. Assess Current Infrastructure Document existing call flows, numbers, and integrations before migration.

    2. Plan Number Porting Coordinate with carriers early - number porting can take 2-4 weeks.

    3. Train Users Teams calling is intuitive, but training ensures adoption and productivity.

    4. Monitor Quality Use Teams analytics to track call quality and address issues proactively.

    The Partner Opportunity

    Resellers who master Teams integration position themselves as strategic advisors, not just product sellers. The opportunity extends beyond initial deployment to ongoing support, training, and optimisation.
