Answering my own question, parking the call with "uuid_transfer <uuid> -both 'park' inline" first keeps the other leg busy and things won't hang up.<br><br>-Anders<br><br><div class="gmail_quote">

Hello fellow FreeSWITCH users,<br><br>I'm using FreeSWITCH Version 1.0.trunk (16883) and I'm using the event socket to break an in-progress call into two independently controlled legs. I want to be able to work with each leg completely independently - hanging up one without affecting the other. Per the docs: <a href="http://wiki.freeswitch.org/wiki/Mod_commands#uuid_transfer" target="_blank">http://wiki.freeswitch.org/wiki/Mod_commands#uuid_transfer</a> I'm using uuid_transfer with an inline lua script to work with one leg without hanging up on the other. I'm setting "hangup_after_bridge" to false on both channels and invoking uuid_transfer with the -bleg option but as soon as I transfer, FreeSWITCH hangs up on one of the legs.<br>
<br>Here's what I'm sending on the event socket. (everything gets an "OK" response from FreeSWITCH)<br><br>Set hangup_after_bridge:<br><br><br>api uuid_setvar 53d37581-1f90-44bf-860a-addbc8430e3a hangup_after_bridge false<br>
api uuid_setvar 9d1a4f2d-2ce6-40e5-ac84-62ad8c2d4654 hangup_after_bridge false<br>
<br>And then do the uuid_transfer:<br><br>api uuid_transfer 53d37581-1f90-44bf-860a-addbc8430e3a -bleg 'lua:callee.lua' inline<br>
api uuid_transfer 9d1a4f2d-2ce6-40e5-ac84-62ad8c2d4654 -bleg
'lua:caller.lua' inline<br>
<br>
The callee leg (53d37581-1f90-44bf-860a-addbc8430e3a) is immediately hung up and the caller leg runs fine. Here's the log messages: (6505551212 is the caller and 5165551212 is the callee)<br><br>2010-03-03 21:29:56.086319 [DEBUG] switch_ivr.c:1441 (sofia/external/+<a href="mailto:16505551212@192.168.27.72" target="_blank">16505551212@192.168.27.72</a>) State Change CS_EXECUTE -> CS_ROUTING<br>
