Overview of Voice over IP (VoIP) and Network Protocols

Unnamed Registration. A telephone registered with Unnamed Registration has the following characteristics:

only one call appearance,

no administrable features,

can make only outgoing calls, subject to call server Class of Restriction/Class of Service limitations, and

can be converted to normal “named” registration by entering a valid extension and password.

More details about the installation process are available in the 4600 Series IP Telephone Installation Guide and in Chapter 3: Requirements of this document.

TCP/UDP Port Utilization

Like most network equipment, the 4600 Series IP Telephones use a variety of protocols, particularly TCP and UDP, to communicate with other equipment in that network—numerous different types of servers, routers, other telephones, etc. Part of this communication identifies which TCP and/or UDP ports each piece of equipment uses to support each protocol and each task within the protocol.

Depending on your network, you might need to know what ports or ranges are used in the 4600 Series IP Telephones’ operation. Knowing these ports or ranges allows you to appropriately administer your networking infrastructure. In this case, you will find the following material useful.

In Figure 1, Figure 2, and Figure 3:

The box on the left always represents the 4600 Series IP Telephone.

Depending on the diagram, the boxes on the right refer to various pieces of network equipment with which the telephone can (or will) communicate.

Open-headed arrows (for example, ) represent the direction(s) of socket initialization.

Closed-headed arrows (for example, ) represent the direction(s) of data transfer.

The text the arrows point to identifies the port or ports that the 4600 Series IP Telephones support for the specific situation. Brackets identify ranges when more than one port applies. In addition, the text indicates any additional qualifications or clarifications. In many cases, the ports used are the ones called for by IETF or other standards bodies.

Many of the diagrams’ explanations refer to system parameters or options settings, for example, IRSTAT or DIRSRVR. See Administering Options for the 4600 Series IP Telephones in Chapter 4: Server Administration for more information on parameters and settings.
