<p>That's really strange, the CANCEL has the same direction as
INVITE, not the opposite. Can you double check if they really
asked for such things. This is very clear in terms of SIP specs
and I doubt that someone understood it wrong.</p>

<p>To be sure I understand properly: do they require to
send a CANCEL back to them for calls that they

how do you cancel/end an early state

self-generates a proper CANCEL towards

`408 Request Timeout' with a different

<p>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.</p>

<div><br>
</div>
<div>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(). </div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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`.</div>
<div><br>
</div>
<div>Any suggestions what can be done
about it?</div>
