So what is the actual state of the channel and ConfBridge at that

Is it listening to music on hold? Is there no other channel present? 
Have you looked at the core debug to see what the audiohooks API is 
saying? Ultimately that's what is capturing the audio and making it 
available for ChanSpy and it has no idea of ConfBridge or Dial or etc,

audiohooks, and then go from there. In a general sense from the 
available information I would say it is a bug, though I am aware that 
this has worked for other people without problem.

Hi Joshua,

The current state of ConfBridge is that it there is one caller, and I'm 
ChanSpying to that caller's channel, wishing to grab the audio coming in 
from the endpoint that's sending audio to at this point, an empty 
ConfBridge.--

[asterisk-dev] ChanSpy / ConfBridge limitation

2024-01-14 Thread Mark Murawski 

Howdy -dev,

Looking for a starting point to investigate this issue:

Using the following AEL (and Running straight-dialplan results in the 
same issue)


context services {
  2802 => {
Answer();
Set(GLOBAL(foo)=${CHANNEL});
ConfBridge(Agent-PJSIP/2802);
  }

  9000 => {
Answer();
ChanSpy(${foo},qoSE);
  }
}

PJSIP/2802-3b18 -> ConfBridge("Agent-PJSIP/2802")
 joined 'softmix' base-bridge 
<56974564-b175-4b6a-93fc-fe4753082213>
 joined 'softmix' base-bridge 
<56974564-b175-4b6a-93fc-fe4753082213>

PJSIP/trunk-bob-3b19 -> ChanSpy("PJSIP/2802-3b18,qoSE")
Spying on channel PJSIP/2802-3b18
Attaching spy channel PJSIP/trunk-bob-3b19 to PJSIP/2802-3b18


Issue:
  No audio is flowing from Spied-on PJSIP/2802-3b18 to the spy-er 
PJSIP/trunk-bob-3b19


If for example, you change 2802 to the following:

  2802 => {
Answer();
Set(GLOBAL(foo)=${CHANNEL});
Dial(PJSIP/2803);
  }


Wait for the call to connect/answer
  PJSIP/2802-3b20 -> PJSIP/2803-3b5d (callee answered)

And then run the same ChanSpy with options qoSE, resulting in:
  PJSIP/trunk-bob-3b97 -> ChanSpy("PJSIP/2802-3b20,qoSE")
  Attaching spy channel PJSIP/trunk-bob-3b97 to PJSIP/2802-3b20


Result:
  Audio IS flowing from spied-on PJSIP/2802-3b20 to the spy-er on 
PJSIP/trunk-bob-3b97



One might say: Well, ChanSpy/ConfBridge don't mix... but then if you do the 
following... this DOES work:
  
context services {

  2802 => {
Answer();
Set(GLOBAL(foo)=${CHANNEL});
ConfBridge(Agent-PJSIP/2802);
  }

  9000 => {
Answer();
ChanSpy(${foo},qwSE);
  }
}

Changing the option from 'o' to 'w', allows you to whisper to PJSIP/2802




Goal:
  Extract out an individual speaker's audio that's going into a ConfBridge
  (Cannot join the bridge as a member, because then you're getting all 
participants audio)


Summary:
  1) You can whisper to a channel that joined a ConfBridge
  2) You cannot listen to the audio from a channel that joined a ConfBridge


Also:
  I tried ChanSpy()'ing into both CBAnn/...;1  and CBAnn/...;2 and I could not 
get audio from here either


Is this a bug or a limitation/missing-feature?


What would be a good place to look into for resolving #2 ?


Thanks!
