Hello all,
I am running into a strange problem with message (or transaction) flags.
I set a message flag while processing the INVITE, but this flag does not
appear in any messages that belong to the same transaction. I discovered
this while trying to resolved an issue with Re-INVITEs. Now I am testing
it with a simple INVITE-CANCEL senario and I see that again the flag
does not appear when processing the CANCEL. My script is pretty basic,
at least for the CANCEL processing. The debug output is at the end of
the email.
if (is_method("CANCEL")) {
if (!t_check_trans()) {
# Must be a CANCEL for a transaction that has
not been established.
# Drop it and the client will resend it.
exit;
}
else xlog("L_ERR","$rm: tran found flags=0x$mF
bflags=0x$bF\n");
....
t_relay();
}
Searching on the internet I came across this

So what is the story? Am I doing something wrong?
thank you for any help
