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.

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.

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.
