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

Thanks,

Is it possible to add an header reason in a cancel?

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

...

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"); }

}

Does it work?

When I use forward, it doesnt work! I don't know how to do

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.
