A blank is heard during the playback of an audio message when escalating a call to a conference

Contributor

Hi,

 

I'm having trouble again with a simple scenario involving cloud communication. I'm still using directly the GRAPH API, without SDK.

This thread references this other one here.

 

A PSTN caller calls a bot, that answers then escalates the call to a conference by inviting a user, or several users from its tenant. While escalating to a conference, the bot plays an audio file for the caller, using the playPrompt GRAPH API route.

 

This works well, except that one hear a blank during the playback, at the exact moment the call is escalating to a conference. I suppose it is when escalating cause it happens only when the first user is invited, not for the others.

 

Regards,

@Mad_hatter - Could you please share which sample you are referring for this?

@Nivedipa-MSFT- I do not refer to any sample. I just do the following

 

  1. A public number (the caller) calls the bot public number.
  2. The bot answers the call using this
  3. The bot plays an audio message using this
  4. The bot invite a new participant escalating the call to a conference (or a group call) using this

Result: the audio message is played fine, but the caller hears a blank during the playback when the new user participant receives the invitation to the conference.

 

If you invite other participants to this group call (step 4/ again and again), no more "blank" will be heard from the playback.

@Mad_hatter - Could you please share how you are calling from public number to bot public number? What actually you have used for it?

@Nivedipa-MSFT- I just used my cellular phone. I'm located in France.

Here is a full log extraction of all JSON communications between my public web site and microsoft cloud, except for token acquisition.

All timestamps are UTC. I've hidden my company name, my company tenant id, and my personal phone number (XXX, YYY and ZZZ)

<<<<<<<<<< is a HTTP communication from microsoft cloud to my web site.

The first call of INVITE_PARTICIPANT at 12:19:14.523 produces a blank during the reading of audio file audio_01.wav. The second call of INVITE_PARTICIPANT at 12:19:22.624 does not.

@Mad_hatter - We tried to repro this issue. Whenever I am calling playprompt garph API only that time I got the callback for playprompt. But When I am calling invite participants the playprompt callback not getting at our end. 

@Nivedipa-MSFTWhere do you get the callback problem from ? I have no callback issue in this case, I'm a bit confused ...

My bot plays an audio message to the caller using GRAPH API. When the bot escalates the call to a conference, by inviting a TEAMS user, the caller hears a small blank during the audio message playback. That's all.

You have all the message exchanges in JSON format between the bot and microsoft cloud.

@Mad_hatter - Could you please share any Demo Video So that we can get exact issue?

@Nivedipa-MSFT- Please find attach a video where you can see

  1. 00:00 A TEAMS client calling the bot (left side of the screen).
  2. 00:10 After the ringing tone, the bot answers and starts playing an audio message.
  3. 00:16 While inviting another user to this call (on the top right corner), one can hear a small "blank" during the playback.
  4. 00:26 Another user is invited (on the bottom right corner), there is no "blank" this time.
  5. 00:36 Another user is invited (on the top right corner), there is no "blank" this time.

Solution

@Mad_hatter 

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

Great, thanks. Could I have a feedback concerning my other problem ?

The problem with the roster empty ?

@Mad_hatter - Could you please share the detailed repro steps for this roster empty issue?

@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.

@Mad_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-MSFTI don't understand the acronyms PMA, CC and MC. But I'm glad to here that you plan to fix this issue !
