Ports and Protocols of Third-Party Products

The information about third-party products is given for convenience without any guarantee of accuracy, and it is subject to change without notice. Refer to the manufacturer for authorized information regarding each device, model and version.

In H.323 environments, H.245 tunneling is recommended to avoid dynamic negotiation of H.245 ports and thus to narrow the TCP port range, provided that the devices support H.245 tunneling..

Server Components and Services

Windows authentication is used by default for communication towards SQL databases, and it is also strongly recommended. See Microsoft Windows documentation about issues concerning SQL and authentication.
