Configuring Option 184 parameters for the client
To assign calling parameters to DHCP clients with voice service, you must configure Option 184 on the

To configure option 184 parameters in a DHCP address pool:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter DHCP address pool view. dhcp server ip-pool pool-name N/A
3. Specify the IP address of the
primary network calling processor. voice-config ncp-ip ip-address
By default, no primary
network calling processor is
specified.
After you configure this
command, the other Option
184 parameters take effect.
4. (Optional.) Specify the IP address

Configuring self-defined DHCP options
CAUTION:
Use caution when configuring self-defined DHCP options because such configuration might affect DHCP
operation.
You can self-define options for the following purposes:
• Add newly released options.
• Add options for which the vendor defines the contents, for example, Option 43.
• Add options for which the CLI does not provide a dedicated configuration command. For example,
you can use the option 4 ip-address 1.1.1.1 command to define the time server address 1.1.1.1 for
DHCP clients.
• Add all option values if the actual requirement exceeds the limit for a dedicated option
configuration command. For example, the dns-list command can specify up to eight DNS servers.
To specify more than eight DNS servers, you must use the option 6 command to define all DNS
servers.
To configure a self-defined DHCP option in a DHCP address pool:
