Configure a VTC for Interoperation with Skype for Business Server

  • Article

Summary: Configure the VTC devices to work with Skype for Business Server.

You will need to perform the following configuration customization procedures for each VTC that will connect to the Skype for Business VIS server through a SIP trunk and Cisco Unified Communications Manager (CallManager, or CUCM) video gateway.

The settings described here are meant only as examples of how CUCM can be configured to work with a VIS. Other settings and/or usages of alternate CUCM functionality could also be used to achieve the same result. No recommendation is implied as to the optimal configuration for a particular scenario.
