Class MediaPortManager

Class for managing allocation of UDP and TCP ports for audio, video, RTT and MSRP media.

This class increments port numbers within a specified range of ports. When the last port in a range is allocated, this class wraps around to the starting port number.

There is no need for the user agent using this class to free ports that have been used for a call.
