We’ll be making some changes to Teams Direct Routing.
Note: Starting on January 3, 2022, Direct Routing will stop processing SIP requests which have Replaces headers.
When will this happen
We will begin this change in early January ’22 and expect to complete mid-January ’22.
How this will affect your organization
When this change is implemented, Direct Routing will reject SIP requests that have Replaces headers defined.
What you need to do to prepare
Please check your Session Border Controller configuration and be sure that you are not using Replaces headers in SIP requests.
