I am just starting a practice and decided to go with Vocalocity for my VoIP. Their rates are pretty competitive. No contracts, month to month. I bought 5 of the Linksys SPA942 for $159 each. Where did you get them for $105? Zingo has them for $179. I will let you know more about the service as I use it. I literally just plugged the phones in.

Packet 8 sent me an email for $250 per year per extension for unlimited calls which is a good deal. I don't know about their service. Vocalocity is $34.99 per extension unlimited.

How is Zingo?

I don't have the voicemail package you have, but I have voicemail included in Vocalocity's monthly price.
