ok, I was reading that he wants to get
just one reason header, not one dynamic

<br>
Just looked briefly, this seems to be the
code:<br>
<br>
t_msgbuilder.c<br>
/* Build a local request based on a

ACK and local CANCEL<br>

char *build_local(struct cell

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>
