Redirecting SIP calls from another SIP server to Teams user

New Contributor

I am trying to understand if SIP calls can be transferred/redirected from a another/thirdparty SIP server to a Microsoft Teams user.


I was reading below links:


As per my understanding we need to use Direct routing, and for direct routing Microsoft certified SBC need to be configured along with the SIP proxy.


But if we have the URL for the Microsoft Teams SIP Endpoint and the credentials to access it, can we transfer calls from another SIP server by configuring the URL and credentials? Will it work or is this supported?


I have below questions:

1. Can we transfer the SIP calls from another SIP server to Microsoft Teams user?

2. If it is possible what are the available ways of achieving this?

3. Do we need to have SBC configured for having this functionality, is it must?

4. Is there a document which explains this process step by step?
