The phone service has to be provisioned to your Fibre account, and your current copper landline account will be switched to Fibre. The phone output on the ONT becomes point 0 of your home phone wiring, and all your house phone wiring will need to be connected to it.
@cdnstudent22 You got fiber internet and tv right but no land line. Later have phone hooked up phone jacks now work. Your phone is hooked up to the old copper from pole. You have to ask to have phone hooked to fiber. Then copper line to house is disconnected and internal house phone wires are hooked to ONT.. You have internet on fiber phone on copper at the moment.
