USING OPTION 77 USER CLASS ON THE IP PHONE
DHCP Option 77 User Class is sent in DHCP request packets from the phone to the
configuration server. This Option 77 defines specific User Class identifiers to convey information
about a phone’s software configuration or about its user's preferences. For example, you can
use the User Class option to configure all phones in the Accounting Department with different
user preferences than the phones in the Marketing Department. A DHCP server uses the User
Class option to choose the address pool for which it allocates an address from, and/or to select
any other configuration option.

Changing the “

” field requires a reboot of your phone.
Notes:
1.
If the User Class is not specified (left blank) in the DHCP request packet, the phone
does not send the User Class DHCP Option 77.
2.
Multiple User Classes inside a DHCP Option 77 are not supported.
3.
DHCP Option 77 may affect the precedence of DHCP Options, dependent on the
DHCP Server.
