Most (if not all) uuid_ API commands are implemented in mod_commands.c.  Session recording is implemented in switch_ivr_async.c.  Changing uuid_record shouldn&#39;t be too difficult.<div><div><br>Chris<br><br><br><div class="gmail_quote">

<div dir="ltr">It&#39;s global in the scope of the channel (from the perspective of individual bugs). I don&#39;t think &quot;you shouldn&#39;t be invoking this async interface from multiple places&quot; is a fantastic argument. The fact is it *can* be, and so we should tighten up this race condition if we can. Can anyone provide guidance on how to add this as an argument to uuid_record, while falling back to the channel variable?</div>

is there a way to invoke uuid_record through bgapi, setting RECORD_STEREO to true as a local parameter instead of using uuid_setvar, over inbound Event Socket?<br>
I would prefer to not set a global state on the channel if possible.<br>
Thanks!<br>
