Software Requirements 3
The following software is required for 4600 Series IP Telephones to work properly.
DEFINITY®/MultiVantageTM Release 8.4 or later software, as appropriate. The H.323 and IP
station customer options must be turned on.
The DHCP server and application should be installed and properly administered, as described
in DHCP on page 4-6.

WARNIN G:

A DHCP server is not mandatory, but static addressing is necessary when a DHCP
server is unavailable.
Due to the difficulties associated with static addressing, it is very strongly recommended
that a DHCP server be installed and that static addressing be avoided.
The TFTP server and application must be installed and properly administered, as described in
TFTP on page 4-17.
For 4630 IP Telephone environments, if users are to have access to LDAP directories or
corporate Websites, the appropriate servers must be in place, and the 4630 telephones must
be appropriately administered in accordance with Chapter 4, Server Administration.
Ensure that all required parameters are configured correctly. For DEFINITY/MultiVantage, see
your administration documentation. For the DHCP and TFTP servers, see Chapter 4, Server
Administration.
Figure 3-1 on the following page illustrates a sample configuration using the 4600 Series IP
Telephones.
