Yealink VC110 - Using the VC110 Video Conferencing Endpoint

Configuring Network
75
A firewall protects an organization‘s IP network by controlling data traffic from outside
the network. Unless the firewall is designed to work with video conferencing equipment,
you must configure the firewall to allow incoming and outgoing traffic to the VC110
endpoint through the reserved ports. Users placing calls through a firewall to endpoints
may experience one-way audio or video if the firewall is not properly configured.
You must configure your firewall to allow incoming and outgoing traffic through the
following ports:

By default, the endpoint communicates through TCP and UDP ports in the 50000 - 54999
range for video, voice, presentations, and camera control. The endpoint uses only a
small number of these ports during a call. The exact number depends on the number of
participants in the call, the protocol used, and the number of ports required for the type
of call: video or voice.
