This is a very new concept - Allow us to give you a virtual PBX where we manage the phone system for you. You do not need a phone system, simply use phones in your offices and homes, connect them over the internet to our hosted server and we will connect them into a unified system.

This service is very popular with companies who's users are often on the road, work from a variety of locations and home. It also works internationally and you can even get your mobile phone to connect in over WiFi
