CM1150v plugged into wall phone outlet but no phones in house work
I have the CM1150v modem with voice, have xfinity voice service. If I plug a phone into the back of the modem, phone service works. I need to connect the modem to my wall jack to serve all the phones...

Nope, never had DSL. We had xfinity years ago, switch back to traditional phone line, just switched back to xfinity voice. Wires are fine, as I've already stated. Phone plugged into line 1 on back of modem works. Line 1 & 2 lights on modem are solid lit. When I plug cord from line 1 into wall, it doesn't power rest of house phones. Finally have some time to do more troubleshooting so will update as I've narrowed it down to 2 things.

Be sure your phone line cable between the modem and the wall jack is good. I recommend the 4 wire/pin cables over any two wire cables.
