As far as I can tell from RFC 3264, when an RTP packet is sent, the payload numbers must be as requested by the *recipient* in its SDP; the sender's SDP is only advisory with regard to payload types. So if sipxtapi says it's listening for DTMF with type 96, the DUT should send with type 96, and sipxtapi should accept it. This may be a significant problem with media handling...
