Primarily geared towards those with Google Voice and an Obi device, http://www.obivoice.com/ has a deal for one year unlimited in/outbound service for $40.00, or 2 years for $60.00. They are a subsidiary of Intelafone. They will port your GV number or, as I found out, give you a new DID at signup. You get a 60 minute/30 day free trial, so you can test their service. I located this deal on the other board, and of course, am trying the free trial. The outbound trunk was easy to setup but the inbound SIP header is blank (so far in my testing). So I think this offer is really geared to the OBI devices.
