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.
Cheers,
Daniel

Yes Daniel, that is precisely so.

To be sure I understand properly: do they require
to send a CANCEL back
to them for calls that they initiate with the first INVITE and do not get
200ok, but 3xx/4xx/5xx?

Looks like it's going to be another battle with a Metaswitch-based
carrier... so far they are telling me 'we can't do anything about it. Send
us a CANCEL to tear down the call`
I know this is a `another story` question, but if I had to overcome this,
would *uac_req_send() *be my only option?
Thanks again,

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?
