    Hi,

     

    I have a trouble setting up OCS pstn communication over Audiocodes gateway MP 114.

     

    If I call from ocs communicator to the pstn, everything its ok, but from pstn to ocs, there is no audio on the call. There is ring back from the ocs, and the call is established, but, there is no audio on both ways of the call.

     

    I´ve captured the traces over this calls, but i dont see any problem there.

     

    On some other platforms, the gateway should be attach as a trusted end point of the pbx to receive call, is there something that im missing?

     

    Regards

    I´ve been analysing the pstn to ocs log, and the only thing that is weird its, over the ack package:

    Did you configure SIP to use TCP and the codec to use uLaw on the MP114
