Configure DHCP Records for Multiple Phone Model Recovery

Some environments use multiple models requiring recovery mode. For example, some environments use AudioCodes, Genesys, Interaction SIP Station I, and Interaction SIP Station II phones. Each requires a different Option 67 value. To handle the conflict, environments using multiple models need to set up Option 67 according to Vendor Class.

You must be familiar with DHCP server configuration and have required domain administrator permissions to complete the network configuration procedures.

To configure DHCP records for multiple phone model recovery

1. Right-click the IPv4 container on the DHCP server and then click Define Vendor Classes.

   

2. Click Add...

3. Type a Display name.

4. Click under ASCII.

5. Type the Vendor Class (e.g. SIP100, SIP200, or 420HD).

   

6. Click OK.

7. Click Close.

8. Right-click the IPv4 container.

9. Click Set Predefined Options...

   

10. Set the Option class to the Vendor Class that you previously created in this procedure.

    

11. Click Add...

12. Type a descriptive name for Option 67.

13. Set the Data type to String.

14. Type Code 067.

    

15. Click OK.

    When the phone boots up, it identifies its Vendor Class in DHCP Option 60 of the Discover. The DHCP server uses this value to match the appropriate Option 67.
