Hi,
Is it possible to add an header reason in a cancel?
We receive a CANCEL without header reason and we need to forward to
another SIP proxy with the reason header?
We use this code in my conf:
if(is_method("CANCEL"))
{
if(!is_present_hf("Reason:"))
{
xlog("L_ERR", "reason missing");
append_hf("reason: Q.850; cause=31\r\n");
xlog("L_ERR", "add raison");
}
}
Thanks,
regards,

I don't know of anything in RFC 3261 prohibiting additional headers in
any initial request.

}
Does it work?

The code does not work.
The header doesn't appear in the cancel forward.

I think in tm mode this not possible. The CANCEL gets autogenerated by
Kamailio so you can not modify it in script.
sip-router trunk has now support for Reason header, but only generating
it automatically or copy it from received CANCEL.
A workaround would be to have the proxy running in stateless mode (no
t_relay() but use forward()[1]) - then you can manipulate the CANCEL and
then forward it.

Hi François!

It works fine for me:
route{
if (is_method("CANCEL")) {
if (!is_present_hf("Reason")) {
xlog("L_ERR", "reason missing");
append_hf("Reason: Q.850; cause=31\r\n");
xlog("L_ERR", "Reason added");
}
forward();
exit;
}
Note: above code snippet only works if the proxy does not do any
parallel forking of the INVITE. It may also be necessary to change the
request-URI to forward the request to the same destination as the INVITE.
