VoIP helps enterprises in lowering the expenditure on travel and communication between branch offices. Here, we show you how to deploy an Open Source and free Asterisk IP PBX, and use it over VPN in a typical branch office.rnThere are different ways in which you can deploy the VoIP server. You can deploy it at a branch or the head office or use a third party service provider who will host it for you. But if you have multiple branches, it is best to have the VoIP server at the head office. It will be easy to maintain and you don't need any extra resource. But first deploy a VPN for a typical branch office scenario. For implementing VPN you will need to have a VPN server at the head office. This VPN server can be a physical server or it can be virtually hosted in your data center.
