VCS Port Reference
The VCS uses different ports and protocols for different services and functions, and many of these are configurable.
The table below shows all the ports on the VCS that are used for each of these services and functions. It shows the default port(s)
and protocol used, and if the ports are configurable it shows the available range and how to configure them via the web UI or CLI.

communication with Peers, even if H.323 is
disabled

Two services or functions cannot share the same port
and protocol; if you attempt to change an existing port or
range and it conflicts with another service, you will get a
warning message.
