Dear All, Hopefully I'll be able to get some help here on re-INVITE in the failure route. For example I have a couple of PSTN gateway options. I'd like to try them by priorities. In case the one with top priority couldn't go through(e.g. returned 5XX on INVITE), I'd like to re-INVITE through another provider in the failure route. Not sure what I should do for such cases. Thanks. Regards,Jay
Are you sure "reinvite" is the correct term for what you are referring to?
A reinvite is an INVITE inside a dialog. A dialog only exists between two parties. So, sending it to a different gateway than the one in relation to which the dialog already exists is not going to work.
That said, you can always fork new branches in a failure_route:
route { ...
t_on_failure("FAILURE");
if(!t_relay()) sl_reply_error(); }
failure_route[FAILURE] { if(t_is_canceled()) exit;
$ru = "<new destination>":
t_on_failure("FAILURE"); t_relay(); }

Hi Alex, Thanks for the quick response. I believe I used the wrong terminology. Your sample code looks like exactly what I'm looking for. Thanks. Regards,Jay

Yep, I think you meant initial (regular) INVITEs, not reinvites. :-)
