Voip adapter with router (Linksys SPA-2102), no dial tone, no phone light, all the sudden. I have tried everything to get it to work, resetting, new lines, EVERYTHING...Everything works but the phones. And yes it is plugged in and set up right...it just stopped working all the sudden.

My VOIP Adapter is lock I can't reach the web page

I disconnected my incoming phone line and connected my VOIP line 1 to my R11 wall phone jack. This feeds the signal to all phone jacks in the house.

I also use the VoIP to fax and send data using my PC modem.
For Fax
Use *99 as a prefix for any number you are faxing or dialing to.
