Re: voip is digital - why use an ata?
An ATA just allows one to use legacy analog equipment with VoIP. I have an analog wall phone in the kitchen that reads off the CID string out loud when a call comes in, that's nice. I also have a multi-handset DECT wireless set, that's nice, too. It works, we only talk to others with cell phones or other PSTN connections so there's no need for HD voice.
As for an ATA that can use "digital sound," if you mean a high def. codec, then no. Analog phones are not able to produce sounds that go outside of the G711 resolution range so there'd be no point.
