Re: [SR-Users] Sending to an announcement server from a failure_route

Hi Aqs, Thanks for the reply. Without the append_branch() the headers are set but the rewritehostport() doesn't work and the request is re-sent to the PSTN gateway.

I'm a bit lost and would appreciate any advice. What I am seeing is two parallel SIP invites, one to my announcement server (hooray!) and one to the PSTN gateway again (which I don't want). How do I stop the original branch from starting again? I've tried changing the order of rewritehostport and append_branch without any difference. I've also tried to use t_relay() instead of the RELAY route. I'm using Kamailio 5.1 and have modified the deafult kamailio.cfg Thanks!
