Holy crap. This is so cool…GrandCentral has added Gizmo support:

• GrandCentral and Gizmo…free calls everywhere
• Got Gizmo? GrandCentral Does
• GrandCentral adds Gizmo Support

I’ve already added mine and tried it, and it works! You could somewhat clunkily do this before if you had a Gizmo CallIn or 775 number, but this is seamless, easy, and all VOIP. It is quite amazing. Even my VOIP phone’s days are probably numbered now. At the very least, I’ll probably change providers (perhaps to another home Gizmo/SIP number; from $25/month to nothing, after a one-time $50 adapter purchase.)
