The 1600 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 

on page 44 for information. At least one address 

in Option 6 must be a valid, non-zero, dotted decimal address, otherwise, DNS fails. The text 
string for the DOMAIN system parameter (Option 15, 

) is appended to the address(es) in 

Option 6 before the telephone attempts DNS address resolution. 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 administering DNS by DHCP, you can 
specify the DNS server and/or Domain name in the HTTP script file. But first SET the 
DNSSRVR and DOMAIN values so you can use those names later in the script.

Note:

Administer Options 6 and 15 appropriately with DNS servers and Domain names 
respectively. 

VLANSEP is “1” 

(On/Enabled)

AND the telephone is 

not tagging frames, 

OR if the telephone is 

tagging frames with a 

VLAN ID equal to 

PHY2VLAN, 

OR if the PHY2VLAN 

value is zero.

The Ethernet switch forwarding logic 

determines that frames received on the 

Ethernet line interface are forwarded to the 

secondary Ethernet interface or to the 

telephone without regard to specific VLAN IDs 

or the existence of tags.

VLANSEP is “1” 

(On/Enabled)

AND the telephone is 

tagging frames with a 

VLAN ID not equal to 

PHY2VLAN, 

AND the PHY2VLAN 

value is not zero.

Tagged frames received on the Ethernet line 

interface will only be forwarded to the 

secondary Ethernet interface if the VLAN ID 

equals PHY2VLAN. 
Tagged frames received on the Ethernet line 

interface will only be forwarded to the 

telephone if the VLAN ID equals the VLAN ID 

used by the telephone.
Untagged frames will continue to be forwarded 

or not forwarded as determined by the 

Ethernet switch forwarding logic.
