Hello,
I'm executing the following code for both the BYE and CANCEL in request_route:
if (is_method("BYE|CANCEL")) { #finished $var(finished) = $TS; append_hf("X-Finished: $var(finished)\r\n"); }
For some reason, the X-Finished header is appended to the BYE, but not the CANCEL. The CANCEL is forwarded further. I have the setflag(22); set, so all outbound messages are sent to the Capture server.
Does append_hf not work for CANCEL requests?

Correct: CANCEL is a "hop-by-hop" request where the proxy is a distinct hop, i.e. UAC sends a CANCEL to the proxy, and the proxy sends a separate CANCEL of its own on the branch that it initiated. This is in contrast to something like a BYE, and most requests, which are end-to-end request that the proxy simply relays upstream as received.

I see, so there is no way to append a header to the CANCEL created by Kamailio?
I tried the onsend_route and branch_route, but none of them worked.

If there is, I don't know it.
Out of curiosity, why would you want to do that?

I want to know when the CANCEL was received by Kamailio, and update the datetime column of the row created by the initial INVITE. It's a custom thing.

What stops you from doing this now? Or do you mean you need to do it on the upstream (and presumably non-Kamailian) UAS?
No, it has to be done in Kamailio. And since there is no way to append a header to a CANCEL, I'm forced to do it another way. I did notice after the CANCEL is sent by the UAC, the UAS generates a 487 Request Terminated. I'm able to append a header to the 487. So, that does solve my problem.

Hello,
there is a tm module that allows setting extra parameters for local ACK and CANCEL:
- http://kamailio.org/docs/modules/stable/modules/tm.html#ac_extra_hdrs
But I think it doesn't support variables -- only static string -- but you can give it a try.
I had in my to-do for a while to add an event route for local ack/cancel where to allow adding headers, but it was no time for it. Maybe you can open a feature request on tracker so it gets higher priority and eventually other devs will look at it.
Cheers, Daniel

A hack would be to loop the CANCEL to Kamailio again and forward it then stateless. When forwarding the CANCEL stateless, you can add headers. regards Klaus
