IP PBX

For PBXs, IP telephony has crossed over from an emerging technology into the mainstream choice for business voice. The initial technical and operational challenges faced by IP PBXs are behind them, ROIs are proving the economics to be solid, and the productivity gains associated with the technology are and will continue to exceed those that could be realized with traditional telephony. User acceptance of IP telephony is high, with the sales of IP lines in the first half of 2007 solidly continuing to outpace those of traditional lines, as the move to IP telephony continues.
