<div>In my case, the problem is related to the fact that the SBC

<div>It is especially important to recover the message: "Call

<div>
<div>The option to forward the call through the stateless loop
works well but it complicates the logic unnecessarily.<br>

<div>So would be great to have a tm function to setup custom
Reason, like below:</div>
<div><i>...</i><br>

t_relay();</i>
<div><i>....</i></div>

<p>iirc, the Reason header should be propagated if it is in incoming
CANCEL, so for this particular case, it should work if you do:</p>
<p><br>
</p>
<p>if(is_method("CANCEL")) {</p>
<p>append_hf("Reason: ...\r\n");</p>
<p>msg_apply_changes();<br>
</p>
<p>t_realy();</p>
<p>exit;</p>
<p>}</p>

ok, I was reading that he

I understood Alfonso's
question to implicitly be: how
can I add a dynamic and
variable Reason header to
outgoing CANCELs?<br>
<br>
Perhaps I was mistaken. But if
I'm not, as far as I know
there is no means of doing
that. Right?<br>
