IP phone from home

We are trying to use a Linksys VPN broadband router to test some IP phones at home. We are connecting to a 3015 concentrator which authenticates the user with a Cisco Secure box. That Cisco Secure box also gives out and IP address. I have not found anywhere to set a Cisco TFTP option 150 like in DHCP to point the phone to our Call Managers. Has anyone ever tried this and if so, how did you do it? I guess I could setup a separate group for the test and tell the concentrator to go to the DHCP server for that group.

Re: IP phone from home

Add Option 150 in Cisco Network Registrar.

Select the DHCP cluster.

Select the Advanced tab and click on Custom Options.

Click Add.

Enter Option number 150 and the Option Data Type of IP address. Click OK.

Click on the Policies tab and select your policy.

Add the custom Option 150.

Enter the TFTP IP address under IP address array.

Click on Always send to DHCP clients.

Enter Yes to commit the changes to the database.
