I have 3 pnone lines coming into the house from 2 different locations & an
addition where new power was used & my cable comes in. I hooked up the box, as instructions stated, got a dial tone, one line worked, then it completely
stopped working, plus, not all my phones were on line, only in two rooms???
The vonage guys from india haven't been much help & when I plug in my fax line, both lines go dead
