Understanding H.323 ALG Media Source Port Ranges

The media source port feature enables you to configure the device to allow media traffic on a narrow or wide range of ports. By default, the device listens for H.323 traffic on a wide range of ports. If your endpoint equipment allows you to specify a sending port and a listening port, you might want to narrow the range of ports the device allows media traffic on. This enhances security by opening a smaller pinhole for H.323 traffic.
