does a business use VoIP if it has already invested in a PBX to manage its calls?
A Gateway device can be added to bridge the analog-to-digital voice signaling. Binary Telecom works with several providers who can assist with the installation of a suitable Gateway. They include InfoArch, Inc and these service companies. The PBX Connect line of products is specifically designed for these customers. New Windows-based, and open-source software can bridge voice and data systems into one. If your PBX is a newer one, and already VoIP enabled, you may be able to use Binary Telecom service with your current system.
