<p class="MsoNormal">Asking again because the loopback method leaves lots of stale sessions over time and I’m using four gigabytes of memory for two hundred calls.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Problem – most (but not all) incoming SIP calls need to hear live announcements (currently coming in via PortAudio) once.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What I’d like to do is have these calls eavesdrop on the incoming audio but with eavesdrop() this stops working as soon as I am bridged into a conference.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>What I have tried:<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Conference auto-outcall to a loopback dialplan to an Announce conference with deaf flags set – these loopbacks keep increasing in number and over weeks lots of orphaned channels persist.<o:p></o:p></p>
<p class="MsoNormal">Eavesdrop a channel – doesn’t last once the incoming call is in a conference<o:p></o:p></p>
<p class="MsoNormal">Making portaudio_stream work on Windows. It crashes on access.<o:p></o:p></p>
<p class="MsoNormal">Making local_stream work on Windows. It needs core Unix-type support.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>What I have not tried:<o:p></o:p></b></p>
<p class="MsoNormal"><b><o:p> </o:p></b></p>
<p class="MsoNormal">Eavesdrop whisper – I don’t think this persists after going into a conference.<o:p></o:p></p>
<p class="MsoNormal">Mod_spy – don’t think it persists after the spy (not the spyee) joins a conference, not sure I can spy on something non-Sofia.<o:p></o:p></p>
<p class="MsoNormal">Conference relate – keeping track of which members of a conference do and do not get this announcement is tricky long term and I’d still need the loopback.<o:p></o:p></p>
<p class="MsoNormal">Converting the incoming audio to an MP3 stream and then streaming to all conferences.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What I want is either a non-session paging, or a uuid_broadcast of a live channel, or the opposite of record – something that persists through changing conferences – so that the outgoing (from FS’s perspective) leg of certain calls always
receives the incoming leg of another, named, fixed call.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone help?<o:p></o:p></p>
