Free to home, a Voice-Over-IP handset (VOIP), or.. jocularly known as "Fart before I pee" technology :P. I was given this phone back in 2005 when me and a mate developed a Telephone voice service for Real Estate advertising based on VOIP and Asterisk software (5 years before smart phones took off). The system got developed, but never got rolled out. We both got full time work in Adelaide (after moving down here) and that ended that. PM me if you're interested, and we'll arrange transport.
