My Duo has dial tone, I can dial out, and it works fine. But when anyone calls me they immediately get an automated message to the effect "the number you dialed is not a working number, please hang-up and check the number." How do I fix this.

Do you hear tones when you press the buttons to dial?Many phones have the option to dial by pulses instead of tones. Make sure your phone is set to tones.

Been a long time since I have seen this phone but I seem to remember a setting like this. Some phones had a long and short setting too.

Activate DTMF tones: Menu > Settings > Initial Setup > DTMF When you dial a number, your phone sends it to your network as Dual Tone Multi Frequency (DTMF) tones. To send DTMF tones during a call, just press number keys or scroll to a number in the phonebook or recent calls lists and press Options > Send Tones

Which make and model of phone is it?
Are you pressing the green call button beforew you try to enter the number you are calling?
You should enter the number first, then press 'green'
You wont hear a dial-tone like a landline phone

If it dials O.K., try pressing # and see if it turns on the DTMF pad. You could have pulse dial on outside calls enabled, and that would keep the keypad in pulse mode until it's told to send tones.

This is really only a guess. The type of dialing is programmed in CO trunks and it's possible it's been set to Call Blocking! It is designed to send pulse only and block the audio of DTMF so the CO won't get confused. You might start with changing the Type Dial to DTMF and test. If that doesn't work, try Pulse and test. Last, if that doesn't work, you will need to keep call blocking and try the # after dialing.

Please comment back if it does or doesn't work. We don't see much pulse dial around here.
