If you are making an inter branch call then it saves the cost of using the regular telephone service. In a VoIP system, the extension numbering is unified. Management is centralized and there is application sharing. This means that all inter-office calls are free and every member or staff can reach all remote staff simply by dialing their internal extension number. This VoIP telephone network can also integrate remote workers, small offices and work from home individuals.
Some of the features of VoIP systems include viewing extension status, use in any location, using voice mail, call recording, and viewing their call history from anywhere.
