Registration and Authentication

The DEFINITY or MultiVantage
Series IP Telephones using the extension and password. For further information, see Related
Documents on page 1-5.

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
server is initiated. This gives 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, a download will result.

WAN Considerations

QoS is harder on a WAN than a LAN. A LAN assumes no bandwidth concerns. A WAN assumes a
finite amount of bandwidth. Therefore, QoS considerations are more significant when the IP
telephony environment includes a WAN. In addition, there are administrative and hardware
compatibility issues unique to WANs.

DHCP and TFTP Servers

The DHCP server provides the following information to the 4600 Series IP Telephone:
IP address of the 4600 Series IP Telephone
IP Address and port number of the TN799 board on the DEFINITY
server. On the call server, the standard port number is 1719.
