VoIP - Unlimited Monthly Service with NO Contract for Only $19.95 or Annual Service for Only $16.95/Month!
 

They're kind of a newcomer to the whole voip scene (although they've got a
rockin' domain name!) and are one of the very few who have very good reviews
AND are offering a monthly service! They give you everything that the others
give you including some more goodies that are not included with the likes of
Vonage (which they clearly advertise here). If you're looking for VoIP service
and don't want to be locked into a full year, you can do so here. UNLIMITED
MONTHLY VOIP SERVICE DEAL

• Update: If you ARE looking
  to go yearly, ViaTalk is still one of the best offers around and have a promo
  running where they'll even buy you out of your contract! 1
