IPKall anyone?

They provide free Washington state area code phone number that you can forward to any SIP account... I have used that in the past with Sipphone (Gizmoproject).

I also learned recently that Gizmoproject allow outgoing calls to some PSTN phone numbers free. They call it backdoor dialing:

I tried it and at least T-Mobile (USA) cell phones can be called free! When I called my T-mobile cell using it, it showed a 660 area code phone number that I could also call back from cell to my VoIP, all without ever purchasing a PSTN number for my sipphone VoIP account.

EDIT: Just in case you wonder, sipphone (gizmoproject) support standard SIP, and I use that account with my Grandstream hardware SIP to PSTN adapter linked to my home phone as second line. The primary line is from Vonage.
