Can't make phone call anymore

[averagejo]

I have Earthlink True Voice phone service (VOIP). It was working for awhile but hasn't been working lately. I have a Series 2 Direct TV Tivo model SIR-S4080R.

Here are my settings:

Dial-In Number 910-XXX-XXXX (local dial-in number)
Dial Prefix 12122773895 (NY dial-in number)
Call Waiting Prefix *99,,*79,,#034
Tone/Pulse Dialing Tone
Availability Detection Off
Dial Tone Detection Off

I know I don't have to make a phone call but I would like to. Any suggestions?

The phone call isn't needed, unless you order PPV via the remote or you need to activate a new software download, which is unlikely at this point in time.
Just delete the nag messages before too many pile up.
