[SR-Users] Copy reason field from 503 to 500.

[Reda Aouad]

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(...);
  ...
}

 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.
