Required Ports

This section describes the specific ports or dynamic port ranges to configure on your RealPresence DMA Edge system and correspondingly on your firewall. The port information is organized based on the different functions, or services, that the RealPresence DMA Edge system supports.

The dynamic source and destination port ranges listed here specify the allowable port ranges for communication between the RealPresence DMA Edge system and other systems and devices inside or outside of your enterprise network. The actual port ranges for your system depend on the number of calls on your license.

A port range for a specific function (for example, LAN-side SIP signaling) indicates the number of ports for that function that must be available to accommodate the number of calls on your system license. You can change the beginning port ranges (within certain parameters) if necessary. If you do so, the RealPresence DMA Edge system automatically calculates the end ranges based on the number of calls on your license.

CAUTION:

The specific ports and port ranges configured in the RealPresence DMA Edge system must match the ports configured on your firewall. If you change any port settings within the system, you must also change them on your firewall.
