Re: voip is digital - why use an ata? Sound is analog. There is no such thing as "digital sound".
Converting the representation of sound from analog to digital can take place anywhere you want -- from the phone in your hand, to the CO of the telephone company.

ok ok. not *that* wet behind my ears..
i suppose what i'm asking is more along the lines of: which kind of phone should i be using with my digital voip service? the ones that you plug in a cat5 or rj45 line?
maybe i'm making an assumption here: aren't there some voip adapters that have cat5 *out* to the phone?

No, IP phones plug directly into your router and each is setup directly to your provider(s). Any phone-to-phone handoff or call sharing takes place via settings with the provider.
(Edit: You can have your own pbx on site, like Asterisk, and take care of this call handling and routing yourself. In this case your provider simply is an incoming and/or outbound "route").
That is one point of simplicity with a single line analog setup with an ATA: You can transfer a call from phone to phone using conventional "hold" on phone 1 and just picking up phone 2. You can share a conversation just by picking up the second phone while a conversation is going on via phone 1. |

He's right! I think cat5 you should use for your digital voip service. |
