Hi all,
I have Kamailio connected to PSTN gateway.
Sometimes gateway replies with "503 temporary unavailable". PSTN gateway adds a "reason" header with ISUP code. But according to RFC 3261 kamailio doesn't forward 503 replies transparently. When 503 reply is received Kamailio replaces 503 with a 500 which is created from original request (build_res_buf_from_sip_req). I have tried append_hf from textops module, but it's not working with a locally generated replies.
How can i copy Reason header from 503 to 500 ?
I will appreciate your help with this situation.
Best regards, Vitaliy Aleksandrov.
Hi,
In which route did you try append_hf ? "event_route[tm:local-request]" is the route executed for locally generated requests, I think you should be trying to modify it there.

I have tried to use "append_hf" in onreply_route. How can i use it in local-request ? According to documentation it can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE.
Sorry forgot to mention that kamailio version is 3.0.2, but i have looked at t_repy.c (tm module from 3.2) and didn't find any changes which can help me.

Well 5xx error codes are processed in failure_route and not onreply_route. Not sure though if you can append_hf there.. Give it a try.
FYI, for using a function in event_route (seems not possible for append_hf):
event_route[tm:local-request] { ... append_hf(...); ... }

According to "http://www.asipto.com/pub/kamailio-devel-guide/#c02message_processing" all replies comes to on_reply and if it is negative reply it will be processed in failure_route after onreply_route. But that is not the point i tried failure_route too.
append_hf works great for forwarded replies. But as i understand when kamailio receives final 503 reply it sends 500 reply generated by "build_res_buf_from_sip_req" (it is part of tm code, not dialplan function).
Thanks for your tries to help.
