extensions must be administered for each telephone.

Release 1.5 and subsequent releases of the 4600 Series IP Telephones use single connection
architecture to communicate with the Avaya media server switch. In the single connection
architecture, only one station extension must be administered for each telephone.
Registration and Authentication
The Avaya media server switch supports using the extension and password to register and
authenticate 4600 Series IP Telephones. For further information, see Related Documents

Software
As shipped from the factory, the 4600 Series IP Telephones may not contain sufficient software
for registration and operation. When the phone is first plugged in, a software download from a
TFTP or HTTP server starts to give the phone its proper functionality.
For downloads of software upgrades, the PBX provides the capability for a remote restart of the
4600 Series IP Telephone. As a consequence of restarting, the phone automatically restarts
reboot procedures. If new software is available on the server, the telephone downloads it as part
of the reboot process.
