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 3: Required Network Information Before Installation - Per DHCP Server. 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 3 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). 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 and DNS Addressing.
The file server file path is the “root” directory the server uses for all transfers. 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, do not use item 6 in Table 3: Required Network Information Before Installation - Per DHCP Server.
