Explanation

The base port number to be used by the adapter to assign to a media channel. The adapter will use this value as the base for assigning 480 ports for RTP and RTCP. The base port number should always be an even number.

Note: For DTNA, ports can be calculated as follows:

For trunk T (1…16) and Channel C (1…24 or 1…30)
	RTP  port = ((T-1)*30 + C-1)*2 + Base Port
	RTCP port =  ((T-1)*30 + C-1)*2 + Base Port + 1
