Issue title: Incoming calls from PTSN to Call Queues are silent.
 Issue body: When we receieve phone calls from the PTSN, and we answer it from the Call Queue we will be unable to hear the person on the other end but they can hear us.

We've got a few tickets opened with O365 support at the moment, but I'm pretty sure it's a bug and not a configuration issue as it's happening on Teams Only and Islands.
