Voice over IP Calculator is an interactive resource for engineers and analysts involved in deploying VoIP.  We believe that the majority of information available on VoIP is either at a conceptual level, or has a commercial bias.  It is our mission to bring you a site with free online calculators and technical papers, covering the 'Nuts and Bolts' of Voice over IP.
