Re: Cannot get dial tone on KX-T7730. Intercom feature...
In a TA series system, the lines have to appear on the phone. Press PROGRAM and the CO buttons. Are they assigned? If they are, then you probably have a Class Of Service or Electronic Station Lock issue. Both of them would prevent the phone from getting an outside line.
