Well after a frustratingly long time of getting setup with xNet Fusion and being told that my VFX line is setup and ready to go, I contact xNet Technical Support and they guide me through the Voice Configuration (entering in the Profile Rule).
But after many many restarts and resets my phones still fail to get a dial tone.
The xNet person I was talking to explained that my Linksys WAG54GP2 is getting their config file but it is not saving/applying it for some reason.

Has anyone else had this problem and maybe have a solution??

or is this a hardware fault with my device?
(I really hope not as it took forever to get this one instock, I don't think I can wait another 3 weeks for a new one.)
