About configuring server interworking for Microsoft Teams

Last Updated : Jul 24, 2020 |

You must configure the following server types on Avaya SBC to make connections with Microsoft Teams:

  • A trunk server for the PSTN.

  • A call server for each of the Microsoft Teams SIP proxy servers.

Each of the Microsoft Teams SIP proxy servers act as a call server, so it must be configured with an Avaya SBC interworking profile to provide interworking functionality.

When configuring the interworking profiles, you must configure the following options in addition to any normal interworking options:

  • The Hold Support option in the General tab must be set to Microsoft Teams.

  • The 183 Handling option must be administered with No SDP. This is required so that ringback is heard on trunks.

  • The Refer Handling option in the General tab must be enabled. Usually for Teams, all sub-options of Refer Handling must be disabled or set to None. If required by the PSTN side and the topology, the sub-options can be enabled.

  • The Record Routes option in the Advanced tab must be set to Both Sides.

  • The Extensions option in the Advanced tab must be set to Lync (prior name for Microsoft Teams software).
