The wife and kids will still want a local number so can't drop that.
Who would people recommend?
Mostly be local calling and NZ mobiles
richms: 2talk works for me. I only register the phone when I need to call so no idea on reliability on incoming calls thru the carrier grade Nat.

sbiddle: You will obviously have to request a non CG-NAT connection as VoIP won't work otherwise.
