[nznog] IP to PSTN/Public network gateway.

First question from a new list member (probably go straight to FAQ no?).... Does anyone know of a (preferably) New Zealand based provider that provides an 'IP' to 'public network' and back again gateway service (at a charge or otherwise)? Somewhere we can fire IP voice calls at, that will take the IP voice call and poke it out to the local number, local number being a normal everyday phone connected to the PSTN ? Thanks for any advice Regards Gavin Legge
