Avaya 4600 사용자 설명서

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 

 of this document.

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.

●

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 

 for more information on parameters and 

settings.
