Configure DHCP Option Records

Use this procedure to configure DHCP option records for each of the managed IP phone types. You must be familiar with DHCP server configuration and have required domain administrator permissions to complete the network configuration procedures.

The following example creates DHCP Option 160.

To configure DHCP option records

1. On the computer that functions as the DHCP server, click Start->Programs->Administrative Tools->DHCP, or use Server Manager to open DHCP.

2. Right-click the DHCP server (if using a Windows 2008 server, right-click IPv4) and then click Set Predefined Options

   

3. In the Predefined Options and Values dialog box, click Add.

   

4. In the Option Type dialog box, complete the information.

   

   Name: Name for this record, related to IP phone provisioning.

   Data type: Data type (in this example, String).

   Code: Option record code (in this example, 160).

   Description: Description for this record, related to IP phone provisioning.

5. Click OK.

6. In the Predefined Options and Values dialog box, in the String Value box, type the URL for the IP phones to use to contact the provisioning server (for a Switchover pair, use the provisioning DNS Host (A) record).

   

7. Click OK.

8. Right-click the Scope Options (or Server Options) container and then click Configure Options.

   

9. In the Scope Options dialog box, select the check box for the option record that you created (in this example, 160 IP Phone Provisioning Server).

   

10. Repeat these steps to create the other DHCP option records required for the appropriate managed IP phone type.
