I am attempting to add a Reason header with Q.850 result codes.
Unfortunately, this does not work:
if (is_method("CANCEL")) {
append_hf("Reason: Q.850; cause=16\r\n");
if (t_check_trans()) {
t_relay();
}
exit;
}
If I have to use 3.1.x, does it support sending Q.850 codes?

AFAIK you can not add headers to the CANCEL request as they are created
by tm module based on corresponding INVITE transaction.
There are several functions in tm module to automatically generate
Reason headers:

A workaround would be stateless forwarding, then you can manipulate the
CANCEL as you like.

I saw these, but I do not think they help (as I need Q.850 reason codes)

Can you provide an example? I am not immediately finding a stateless
way to send a CANCEL.
Thank you,

Note: if you want to forward CANCEL stateless, you also have to forward
the INVITE and ACK stateless.

I thought I would need to use forward. Thank you for the confirmation.
Note: if you want to forward CANCEL stateless, you
also have to
forward the INVITE and ACK stateless.
I have to believe a stateless situation would be less than optimal.
I presume to support sending Q.850 result codes 'properly', one would
have to patch the TM module ?
