Re: [Serusers] Race Condition on CANCEL?

No, the UAS (U2) shall answer with 200 OK to confirm that the call has been canceled and yes, it should be sent to U1. Do you have an actual experienced problem or was the 200 OK the problem? g-)

Hello,

Im having some problems with cancelled calls. This is the scenario:

U1 Proxy U2

INVITE -->>> <<--- 100 Trying INVITE -->>>

CANCEL ->>> <<-- 200 Cancelling CANCEL ->> <<-- 180 Ringing <<-- 487 Cancelled <<-- 180 Ringing

    <<-- 200 OK
                                (Wrong??)
                             <<-- 200 OK

My problem is that after some time waiting for "ringing", the user cancel the call. Even that proxy responses "487" it still forward the late 200 OK.

Should it forward? I guess not because the transaction was destroyed, right?

Can it be a configuration problem on my ser.cfg ou it can be in t_relay implementation?

Thanks in advanced. Regards,
