For background information, read Understanding the H.323 ALG.

By default, the J-series 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.
