In any case, both Oooma and Obihai sell hardware platforms that act as VoIP gateways. Both allow you to dial into their hardware platform, and get virtual 2nd dialtone to dial back out. OBi endpoints such as the Obi110 (below) support free calls between one another without the use of a computer.

Interestingly, the Obihai products feature some social network aspects as well. You can add people to your Circle of Trust so they can call via your OBi and you can also ask to be added to a Circle of Trust so you can make calls via their OBi device. So for instance, support you want free calls to London. Find an Obi user in London and request to be in their circle of trust. Likewise, you can allow them into your circle so they can make free calls in your local calling area.
OBiON for the iPhone makes it possible to place and receive free calls to/from other OBi endpoints using the OBiTALK network and your iPhone's Wi-Fi or 3G connection to the Internet. All you need to know is the 9-digit OBi number. Calls with regular land line and mobile phones are possible when using an Obihai OBi Voice Service Bridge device.

If you call an Obihai OBi110 Voice Service Bridge, your call can be bridged (2nd dialtone) to another service like your local Telco or a VoIP service to reach land lines and mobiles.
Your OBiON iPhone app can also receive calls from other OBi endpoints when they dial your 9-digit OBi number. Calls from a regular phone or the PSTN can ring your OBi number by using an Obihai OBi110 Voice Service Bridge.
