    Overview: The VoxSBC can be used to connect Voxtelesys SIP Trunking or your PBX System to Microsoft Teams. Since the Teams Phone System has been released this process has changed multiple times. There are currently two ways of configuring it: mostly using the Teams Admin Panel or mostly using PowerShell. If you prefer PowerShell, we do have a guide on that as well!

    Create the Domain in Microsoft

    1. Make sure your account is set up to support VoxSBC

    You can check this by looking at your registrations on the Portal. You will have a little Teams icon under Options if this is the case. If there is no icon, reach out to [email protected] to update your registration type.

    2. Start the VoxSBC Wizard

    From Portal > Registrations > Click on the Teams icon (under Options) on the domain you want to set up.
