The GAO VoIP Package can easily be customized to suit customers’9 specific requirements.

With all this included in one package, product design engineers can reduce both the cost and time to market of their products.

The GAO VoIP Package utilizes VoIP technology, which allows voice, data, and fax calls to be placed over IP networks. VoIP technology compresses calls down to 5.3 kbps from 64 kbps. The compressed calls are then packetized so that multiple channels of voice can be transmitted over one regular voice channel. The combination of compression and packetization that is possible over IP and other networks makes VoIP much more efficient at utilizing telephone switches, lines, and bandwidth than traditional long distance calls.
