To simplify, the problem seems to come down to the
following: how do
you cancel/end an early state dialog between the caller and callee
after `fr_inv_timeout` occurs? Kam self-generates a proper CANCEL
towards the callee, while the caller gets a `408 Request Timeout' with
a different To-tag.
That's all required not to have a dialog completed, but faild. There is
no need to send a BYE or another CANCEL. The INVITE got the 408, not 200.
Cheers,
Daniel
I've tried:
dlg_bye("all") - throws an error, non-confirmed dialogs can't be
terminated with this function
t_cancel_callid("$dlg(callid)", "$dlg(from_cseq)", "22",
"200") -
doesn't seem to produce any action
Suggestions?

Hi ppl,
Scenario: invite from upstream is t_relayed to a client gateway.
After `fr_inv_timeout` occurs, in a failure route I simply t_reply
with "503 - Service unavailable", then exit().
However, the upstream provider simply ignores this reply, call
doesn't hang up. This doesn't happen when the client's gateway
generates identical 503 or other negative replies.
I suspect this is happening because the To-tag in the Kam
generated 503 reply doesn't match with the To-tag that previously
was forwarded from the client's gateway to the upstream provider
in the `180 Ringing`.
Any suggestions what can be done about it?
