VoIP is the abbreviation for Voice over IP: calling over the Internet. Because of VoIP, you no longer need a separate phone line or physical PBX. In addition, you call reliably and cheaply from anywhere in the world where you have an Internet connection or use 4G. Calls can be made using your landline, laptop, tablet or smartphone with your own internal number.

A complete Unified Communications solution, with features like web conferencing, presence, softphones, smartphone clients and more - without the high costs and administrator problems of an "old-fashioned" PBX.
