[OpenSIPS-Users] Avpops failure route

[Andrew Pogrebennyk]

Hello,

I have a similar setup. It could be that you just need to call 
append_branch() somewhere in the failure_route[3], unless you do it in 
route[4]. At least it works for me.

However I have faced another problem that you can't use the same 
gateway/UA several times as a target for sequential forwarding, since 
INVITEs to different targets are part of the same dialog, besides 
OpenSIPS sends new INVITE a few ms prior to canceling previous branch 
(well, I'm about to submit it as a bug). I thought you could have some 
clue about it since I see you are also using one IP address. I have 
written about it here:
http://www.mail-archive.com/users@lists.opensips.org/msg07999.html
but Bogdan didn't reply yet.
