VoIP Solutions - Free Interbranch Call and Faxing

The below diagram shows ‘free’ inter-branch calls and faxes between the headquarters and the branch level. The calls are very transparent, as all calls are dial directly to the destinated extension numbers without going through the operator/receptionist. No speed dial is necessary as only extensions numbers between the sites are dialed. In other words, it is a virtual private network for voice and faxes over the internet broadband or any IP network.
