Parameter Description
Base UDP Port

Values between 1024-65534 are allowed, and the default value is none. If the value is set to none, the value is inherited from the system-level Media Port Range.

Max UDP Port

Specifies the end of the range of UDP ports to use for RTP/RTCP media for this trunk group. This value must be greater than the value of Base UDP Port and within the system-level media port range. Values between 1024-65534 are allowed, and the default value is none. If the value is set to none, the value is inherited from the system-level Media Port Range.
