  • What is Microsoft Operator Connect?

    Operator Connect brings PSTN calling to Microsoft Teams. It enables small to medium sized businesses to make phone calls and audio conference calls through Teams from a desktop, laptop or mobile phone via their operator-managed service, simplifying comms and improving the user experience for all employees.

  • What is the difference between direct routing and Operator Connect?

    Direct routing enables business users to make and receive calls on Microsoft Teams by linking the platform with a PSTN via an approved partner, like Gamma. It’s a flexible integration option that supports a more tailored approach to call plans (plus additional functionality, such as call centre technology). Operator Connect – a more recent addition to the Microsoft suite – works in a similar way, but allows you to manage call routing services entirely via the Microsoft Teams ecosystem for a more streamlined operation.

  • What is required for Operator Connect?

    Operator Connect is available with selected Office 365 licenses. In order to make use of this tool, you will need access to Microsoft Teams, a Teams Phone System, and an agreement with an approved Operator Connect provide (like Gamma) in order to link Teams to your PSTN carrier.

  • What is Operator Connect Conferencing?

    Operator Connect is a specific plan from Microsoft that allows participants to join Teams meetings by dialling into the call with a PSTN phone number, or dialling out to a PSTN phone number. Any outbound calls must be routed via your operator. You can purchase an Operator Connect Conferencing licence as an add-on to your Teams licence.
