IP phone from home

[brad.miller]

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.
