I've been out of the telco world for too long and I forgot about this infamous analog gateway behavior. http://wiki.voip.ms/article/FAS_(False_Answer_Supervision) <http://wiki.voip.ms/article/FAS_%28False_Answer_Supervision%29>

Right, but the PSTN connects the call and the PSTN is sending AUDIO packets in the form or ringing. As far as the audiocodes is concerned (whether it is a busy signal, error recording or ringing or a person answering the phone) it has successfully completed the call and connected it. It does not and cannot know the difference accordingly (especially if it is an analog line).

    I just checked the scenario and send the behavior...No interop

    sends 200OK before external users answer the call or not..

    Then make up your mind.  Are you reporting an audio code bug or
    investigating why it is connected in CDRs?  It is conencted in
    CDR because IT IS CONNECTED.  If you are investigating audiocodes
    interop with ITSP, please send a packet capture directly showing
    packet exhcnge between this two components and not from home.

    No Joegen,its not successful call.Audiocodes sends 200 OK.Either
    external users answers or not  there will 200OK from
    Audiocodes.So CDR shows Completed instead of Abandon.But this
    behavior is not seen in ITSP...

    This is a successful call.  Why do you expect this to be
    flagged as abandoned?

    There is a chance that this is a race condition on call
    cancellation where CANCEL is being sent while 200 OK is
    already traversing the wire.  In this case, the
call-termination mechanism will be a time-out in ACK. However, CDR will show sucess because it base the connected
    flag on receipt of 200 OK.  If this is the case, then it is
    not a bug.  Too many assumptions here.  a packet capture will
    shed light.

        Hi All,

        Thanks for the reply, so can i raise an issue since the
        call status is displayed as "Completed" instead of
        "Abondoned" when the subscriber hung up before there was
        an answer.

        Thanks

        Subscriber --> PSTN

        and the subscriber hung up before there was an answer,
        then the cdr should say "abandoned".
