Old Touch Tone Phone Can't Make Outgoing Call

[#1]

Hi,

I recently got setup with fios and wanted to use an older phone with it but am unable to make outgoing calls. I have a dial tone and when I push the buttons I hear a touch tone, but the phone doesn't make the call and ends up going to a busy signal.

I have tried seeing if it was a polarity issue but doesn't seem to be the case and It shouldn't be too old because the phone isn't pulse dialing.

Would really appreciate some help or if other people have had success using older phones with fios

Have you tested whether your old phone is functioning correctly?

Polarity won't be an issue on fios. Do you have another phone to try. The issue is likely with the phone.

I believe so. I can receive calls and the voice sounds great. I haven't tried it on a different line because I don't know anyone else who has fios home phone

It would just seem odd that the phone would be damaged if I can receive calls

Can you take the phone and connect it directly to the ONT? Also you can pick up new phone at Target for $15. It's very unlikely the issue is the ONT.

It’s been connected directly into the ONT. is there a different configuration?
