Once you've set up your VPN network or Internet, you can easily save money on interoffice long distance calling by bridging your voice network to your data network with Sa VoIP Gateway. Sa VoIP Gateway is a point-to-point or multipoint solution (one box is required at each location) that merges voice/fax from traditional telephones onto an IP data network. It then utilizes another VoIP Gateway at the remote end to separate the voice/fax from the data network and send it back to the receiving phone. With Sa VoIP a company can save thousands of dollars on recurring long distance charges.
