Configuring Option 184 Parameters for the Client with Voice
Service
To assign voice calling parameters along with an IP address to DHCP clients with voice service, you need
to configure Option 184 on the DHCP server. For information about Option 184, refer to Option 184 .
If Option 55 in the request from a DHCP client contains Option 184, the DHCP server will return
parameters specified in Option 184 to the client. The client then can initiate a call using parameters in
Option 184.
Follow these steps to configure option 184 parameters in the DHCP address pool:
To do… Use the command… Remarks

Configuring Self-Defined DHCP Options
By configuring self-defined DHCP options, you can
• Define new DHCP options. New configuration options will come out with DHCP development. To
support these new options, you can add them into the attribute list of the DHCP server.
• Define existing DHCP options. Some options have no unified definitions in RFC 2132; however,
vendors can define such options as Option 43 as needed. The self-defined DHCP option enables
DHCP clients to obtain vendor-specific information.
• Extend existing DHCP options. When the current DHCP options cannot meet the customers’
requirements (for example, you cannot use the dns-list command to configure more than eight DNS
server addresses), you can configure a self-defined option for extension.
