Other Network Considerations

TCP/UDP Port Utilization

The 9600 Series SIP IP Telephones use a variety of protocols, particularly TCP (Transmission Control Protocol), UDP (User Datagram Protocol), and TLS (Transport Layer Security) to communicate with other equipment in the network. Part of this communication identifies which TCP or UDP ports each piece of equipment uses to support each protocol and each task within the protocol. For additional TCP/UDP port utilization information as it applies to Avaya Communication Manager, see UDP Port Selection on page 39.

Depending on your network, you might need to know what ports or ranges are used in the operation of 9600 Series IP Telephones. Knowing these ports or ranges helps you administer your networking infrastructure.

Note:

In many cases, the ports used are the ones called for by IETF or other standards bodies.

Many of the explanations in Table and Table refer to configuration parameters or options settings. For more information about parameters and settings, see Administering Options for the 9600 Series SIP IP Telephones.
