0x01DF UDP Source Port Validate

Use this TLV to enable a VoIP media stream to be checked for its validity by authenticating the UDP source port of the incoming packets. The default value is 1 and implies that the UDP source port validation is performed on the received packets. By setting the value of this TLV to 1, the UDP source port field in every received packet (whether RTP, RTCP or T.38 packet) is validated.
