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.  However, when calling the voice user directly (not through the AA), the caller hears ringing.  

Is there a setting to maintain the caller hearing either ringing OR hold music when transferred from an Auto Attendant to another Voice User that I might be missing.  I have music on hold setup with an audio file.  It is almost like it is not on hold, but not really ringing (for the caller).   And yes, even if it is dead silent while ringing the voice user, if the voice user answers, the caller is connected.  So it is just something with being redirected from an auto attendant to a voice user.

  • 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.
