Will Corded Phone Work In Power Outage After Switching from DSL to ATT Fiber Internet?
I have ATT DSL. My coded phone works during a power outage, no matter how long the outage lasts. No power needed. No battery backups needed. I plug the phone into the phone jack and it works. After switching to ATT Fiber Internet will the corded phone still work this way or will it be dependent on power and only work as long as a battery backup lasts? Can anyone give me a definitive answer on this?
