Hi Anthony, Thanks for the reply! While waiting for my question to appear on the list yesterday (6H delay at yoda.ostag.org... is first post moderated?) I went deep into the SIP stack and figured out the solution: You just have to give NTATAG_PASS_100(1) as one of the tags for nua_create. Then you get a sofia event for it. I guess the author has made it easier since your last discussion. I have changed my mod_sofia to do this. I also added a channel flag which is set if any response has been received from the remote end (be it 100, 18X, 2XX, etc.). The flag is now tested by switch_ivr_originate to time-out a call quickly. Would you/anyone be interested in a patch to do this? If so please let me know the procedure for posting patches etc. {P^/ On Tue, 21 Apr 2009 at 10:03 -0500, Anthony Minessale wrote:
That 100 trying is handled deep in the sip stack. The author of sofia said it would be a big job to bring that up to the even callback. Someone may be able to persuade him to allow you to pass a global timeout waiting for 100 or something but no solution exists atm

Hi,
I am trying to use FS to make outgoing SIP calls. I have a number of gateways that can make the call. However, if one of them is down or has some other problem then I would like to detect that quickly.
I intended to use the provisional '100 Trying' message for this... if it hasn't been received in a couple of seconds then go on and try the next gateway.
But I can't find a flag/event/state which corresponds to receipt of this message. Can anyone tell me where I should be looking? I put a debug print in sofia_event_callback for every event but there doesn't seem to be one fired for this condition.
Thanks in advance.
