Caller hears silence when redirected from an Auto Attendant to another Teams User.
Maybe someone can help me. If I setup an Auto Attendant to redirect to a voice user in my organization, the caller gets silence on their end. It does not play any ringing, hold music, or anything. ...
The problem in my case had to do with a setting on the side of the carrier. They were not processing a REFER command from the Session Border Controller after redirect of the call. They got it fixed after some testing with them.
To clarify the ring-back is not heard while waiting for the call to be answered. This is a Direct Routing setup but I have no control over any Direct Routing settings.
