Solved Changes to Direct Routing and processing of SIP requests

[h4x]

Good morning,
I received an update over the weekend which noted the following:

Note: Starting on January 3, 2022, Direct Routing will stop processing SIP requests which have Replaces headers.

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.

This is also updated on Microsoft's Direct Routing documentation

Since I don't know how 3CX is handling these SIP requests while acting as the SBC for Teams, I was hopeful that someone more knowledgeable might be able to comment?

Thanks!

Hi!

I have spoken with our Dev Team and apparently there is nothing to worry about. We already create the Teams objects without 'Replaces' so we should be OK.
