48 4600 Series IP Telephone Release 2.2 LAN Administrator Guide
Required Network Information
DHCP is the control point where an enterprise controls its IP telephones. Before administering
DHCP and TFTP, HTTP, and TLS, as applicable, complete the information in Table 2: Required
Network Information Before Installation - Per DHCP Server on page 48. Completing the pre-
installation steps ensures that you have the necessary information regarding your network. If
you have more than one Gateway, TFTP/HTTP/TLS server, subnet mask, and Gatekeeper in
your configuration, you need to complete Table 2
for each DHCP server.
Release 1.5 of the 4600 Series Telephones supported specifying a list of IP Addresses for a
gateway/router, TFTP server, and Avaya media server Gatekeeper(s). We explain this
specification in Overview of Voice over IP (VoIP)
on page 21. Each list can contain up to 255
total ASCII characters, with IP Addresses separated by commas with no intervening spaces.
Note that depending on the specific DHCP application, only 127 characters might be supported.
When specifying IP Addresses for the file server or media server, use either dotted decimal
format (“xxx.xxx.xxx.xxx”) or DNS names. If you use DNS, note that the system value DOMAIN
is appended to the IP Addresses you specify. If DOMAIN is null, the DNS names must be fully
qualified, in accordance with IETF RFCs 1034 and 1035. For more specific information about
DNS, see DHCP Generic Setup
on page 50 and DNS Addressing on page 84.
The file server’s file path is the “root” directory used for all transfers by the server. This is the
default directory all files will be uploaded to or downloaded from. In configurations where the
upgrade script and application files are in the default directory, item 6
in Table 2: Required
Network Information Before Installation - Per DHCP Server on page 48 should not be used.
