DNS Addressing

As of Release 1.5, the 4600 IP Telephones support DNS addresses and dotted decimal
addresses. The telephone attempts to resolve a non-ASCII-encoded dotted decimal IP Address
by checking the contents of DHCP Option 6. See
information. At least one address in Option 6 must be a valid, non-zero, dotted decimal address,
otherwise, DNS fails. The system parameter DOMAIN's (Option 15,
appended to the address(es) in Option 6 before the telephone attempts to resolve the DNS
address. If Option 6 contains a list of DNS addresses, those addresses are queried in the order
given if no response is received from previous addresses on the list. As an alternative to

or HTTP script file. But first SET the DNSSRVR and DOMAIN values so you can use those
names later in the script.
Note:
If you administer Options 6 and 15 appropriately with DNS servers and Domain
