Explanation of Port Ranges1. The "listen_port" value is the port  will listen for incoming connections on.2. The "rtp_port_range" value is the range of UDP ports that  will use for RTP (audio and video communication channels). You can change the UDP port range if you are using IP translation and if you need to have several  running behind your NAT/PAT router.  needs to be restarted for the new values to take effect.3. The "tcp_port_range" value is the range of TCP ports beside the listen_port that  will use for the H.245 channel. You can change the TCP port range if you are using IP translation and if you need to have several  running behind your NAT/PAT router.  needs to be restarted for the new values to take effect. This port range has no effect if both participants to the conference are using H.245 Tunneling.4. The "udp_port_range" value is the range of UDP ports that  will use when registering to gatekeepers. You can change the UDP port range if you are using IP translation and if you need to have several  running behind your NAT/PAT router.  needs to be restarted for the new values to take effect. This port range has no effect if you are not registering to a gatekeeper.
