Avaya 4600 User Manual

As of Release 2.4, 4600 Series IP Telephones support unnamed registration. A telephone can 
register with the call server and receive limited service without requiring an extension and 
password entry. Unless otherwise disabled, the telephone automatically attempts to register 
unnamed if no action is taken on the telephone Extension entry screen. 

A telephone registered without the extension and password has the following characteristics:

●

only one call appearance, preventing conferences or call transfers,

●

no administrable feature buttons,

●

on-hook dialing cannot be invoked, 

●

limited to the calling capability administered for PSA (Personal Station Access) on the call 
server, for example, only outgoing calls permitted subject to call server Class of 
Restriction/Class of Service limitations, and 

●

can be converted to normal, named registration by a valid extension and password entry.

As of Release 2.6, certain IP telephones support the IEEE 802.1X standard for pass-through 
and Supplicant operation. The system parameter 

 determines how applicable 

telephones handle 802.1X multicast packets and proxy logoff, as follows:

●

When DOT1X = 0, the telephone forwards 802.1X multicast packets from the 
Authenticator to the PC attached to the telephone and forwards multicast packets from the 
attached PC to the Authenticator (multicast pass-through). Proxy Logoff is not supported.

●

When DOT1X = 1, the telephone supports the same multicast pass-through as when 
DOT1X=0. Proxy Logoff is supported.

●

When DOT1X = 2, the telephone forwards multicast packets from the Authenticator only to 
the telephone, ignoring multicast packets from the attached PC (no multicast 
pass-through). Proxy Logoff is not supported.

●

Regardless of the DOT1X setting, the telephone always properly directs unicast packets 
from the Authenticator to the telephone or its attached PC, as dictated by the MAC 
address in the packet.
