Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Q. Which ports do TANDBERG Codian products and TANDBERG ConferenceMe use?

A. All TANDBERG Codian products make TCP and UDP IP connections. This article describes the ports used for both connection types.

Ports used by Codian products

Incoming ports

  • FTP - TCP:21 + TCP ephemeral (i.e. dynamic rather than fixed) ports used for passive mode

  • HTTP - TCP:80

  • HTTPS - TCP:443

  • H.323 - TCP:1720 + TCP ephemeral ports for incoming calls

  • RTSP - TCP:554

  • Windows Media Player streaming - TCP:1755

  • SNMP - UDP:161

  • Outgoing H.323 calls involve TCP connections from TCP ephemeral ports to TCP:1720 and a number of TCP ephemeral ports

  • Outgoing SIP TCP calls involve connections from TCP ephemeral ports to TCP:5060

  • Outgoing SIP TCP calls involve connections from TCP ephemeral ports to TCP:5061

  • Outgoing SNMP traps are sent from UDP ephemeral ports to port 162

  • Media (including audio, video and FECC messages) is UDP from ephemeral ports to ephemeral ports.

  • The TANDBERG Codian products allocate ephemeral ports in the range 49152 to 65535. It is possible to change the ports on which Codian products receive and establish connections. For instance, by default Codian products listen for H.323 calls to port 1720 and web browser connections to port 80 but these can be changed. Go to Network > Services.

Outgoing ports

  • RAS - UDP:2222 for gatekeeper client messages and UDP:1719 for the built-in gatekeeper server (if enabled)

Ports used by ConferenceMe

Signaling, including call setup, uses port 80 on the Codian MCU, and an arbitrary port on the PC running ConferenceMe. ConferenceMe will try UDP first for the RTP transport, which uses port 5082 on both the Codian 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 Codian MCU. To configure the UDP service used by ConferenceMe, go to Network > Services and in the UDP service section, edit the Tunneled media option.
