Reserved ports

To place calls to other devices through a firewall, you must configure your firewall to allow incoming and outgoing traffic to the Lifesize system through the reserved ports. Users placing calls through a firewall to systems with public IP addresses may experience one-way audio or video if the firewall is not properly configured to allow two-way audio and video traffic.

By default, Lifesize systems communicate through TCP and UDP ports in the range 60000 – 64999 for video, voice, presentations, and camera control. Lifesize systems use a subset of these ports during a call.

NOTE: The minimum number of required ports is 100.
