A blank is heard during the playback of an audio message when escalating a call to a conference
- This is by design.
From P2P to escalate to conference will trigger a media retarget.
P2P media will be replaced by server side mixer.
This media retarget may take 1-2 secs which will cause a gap or "blank".
After the first invite, it becomes group call. So inviting new participants will not cause any gap again, since server side mixer keeps serving the call.
Thanks,

Nivedipa-MSFT- Please find attach a video where you can see
- 00:00 A TEAMS client calling the bot (left side of the screen).
- 00:10 After the ringing tone, the bot answers and starts playing an audio message.
- 00:16 While inviting another user to this call (on the top right corner), one can hear a small "blank" during the playback.
- 00:26 Another user is invited (on the bottom right corner), there is no "blank" this time.
- 00:36 Another user is invited (on the top right corner), there is no "blank" this time.

- Nivedipa-MSFTMad_hatter - It'll happen whenever PMA gets the RetargetCompletion call from CC. This would happen after the Invite gets accepted but apparently not. CC likely just starts the retarget to MC as soon as it gets the invite. We could change this behavior to subscribe the bot to rosters as soon as we get the invite.
Nivedipa-MSFT- Yes, of course, it is the exact same scenario as above. When the bot escalates the call to a conference, there is a 50% percent chance that no roster is received (or rather a single roster empty) until the first participant accepts the invitation and enter the conference. When running fine, and while inviting participants, I receive usually a roster with the caller and the bot.
This becomes an issue when the caller drops the call before the first participant accepts, cause the bot is then "blind" and doesn't know the fact that the caller has quit.
