Which ports are used by Cisco acquired TANDBERG/Codian Conferencing Products, Cisco TelePresence Serial Gateway Series, and Cisco TelePresence ConferenceMe?

All Cisco acquired TANDBERG/Codian products and the Cisco TelePresence Serial Gateway Series make TCP and UDP IP connections. This article describes the ports used for both connection types.

Ports used by Cisco TelePresence ConferenceMe

Default port allocations

Signaling (including call setup) uses an arbitrary port on the PC that runs ConferenceMe, and by default the following port on the Cisco TelePresence MCU:

Changing the MCU port allocation

You can optionally change the MCU port allocation for ConferenceMe (go to Network > Services).

Important! With MCU version 4.1(1.59) or earlier, ConferenceMe shares the HTTP web port and cannot be configured separately. So if you change the default port number for ConferenceMe then it will also change for the web port.

From MCU version 4.2(1.43) the web port and the ConferenceMe port can be configured separately. By default ConferenceMe can use either the web port or the ConferenceMe specific port. You can optionally override this and specify that only the ConferenceMe specific port may be used (go to Settings > Streaming and uncheck Allow ConferenceMe to use web service).

Transport

ConferenceMe will try UDP first for the RTP transport, which uses port 5082 on both the Cisco TelePresence MCU and on the PC running ConferenceMe, but if this connection fails for whatever reason then the client will use TCP (using the same ports as UDP) for the signaling process.


Note: To allow ConferenceMe to use TCP if the UDP connection fails, select Allow fall back to media using TCP on the Settings > Streaming page.

The UDP port is configurable both on the PC client (refer to the PC's documentation) and on the Cisco TelePresence MCU. To configure the UDP service used by ConferenceMe, go to Network > Services and in the UDP service section, edit the Tunneled media option.

This article applies to the following products:


Note: Cisco TelePresence MCU 5300 does not support ports used by Cisco TelePresence ConferenceMe and Streaming.
