This object configures the static local RTP (UDP) port that the connection uses, restricted to even numbers since odd numbers in that range are reserved for the paired RTCP port, and it must be unique because only one connection is allowed per port. An administrator provisioning a VoIP gateway connection uses this to assign a dedicated media port, ensuring it does not collide with a port already in use by another RTP connection. For example, an administrator would assign port 49650 to one connection and a different even port, such as 49652, to the next connection to avoid a port conflict.
