Hi,<br>
<br>
In my module, I will collect a list of available failover route that I
can use to failover to whenever a particular error is received.
However, these available routes has different condition and the
condition changes every half a minute. Therefore, I need to catch the
hangup cause after bridge, and then figure out the next workable
available route based on the latest condition setting. <br>
<br>
It seems like this is only prossible to be done within a C module. Any suggestion will be greatly appreciated.<br>
<br>

<div style="">Hi,<div><br></div><div>You can set the "continue_on_fail" variable to true (or to the hangup causes you want it to ignore) and it'll keep executing whats queued. <div>For receive_message, unless you hook the session thats being created as a B-leg, you won't get anything relevant. </div>
<div>Also set hangup_after_bridge=true if you want to stop failing over when it worked.</div><div><br></div><div>Im curious, what are you coding? you can transfer the call in the dialplan without having to do all this manual queuing in C, thats why the routing state and dialplan modules exist.

<div> </div> <div>With switch_caller_extension_add_application(session, extension, "bridge", "sofia/gateway/mygw/1232323);, if there is an error ( 503 received for instance ) in the outgoing INVITE, freeSWITCH would leave my module ( or the module's APP) and go on to the next action. Is there anyway to control it so that freeSWITCH would remain to be within the module's APP funtion and continue executing the code after switch_call_extension_add_application, when let's say a 4XX or 5XX or CANCEL ( from originator) is received? </div>
<div> </div> <div>I have tried it and found that if the bridging is successful, freeSWITCH would continue executing the code after switch_caller_extension_add_application, but if an error is received, then it would just move on to the next action. </div>
<div> </div> <div>Does anyone know how to deal with this problem?</div> <div> </div><font color="#888888"> <div>Woody</div></font><br>_______________________________________________<br>FreeSWITCH-users mailing list<br><a href="mailto:FreeSWITCH-users@lists.freeswitch.org" target="_blank">FreeSWITCH-users@lists.freeswitch.org</a><br>
