What is a Digital Voice gateway and do I need one?
A Digital Voice gateway is important for any reasonable-size Digital Voice deployment because it handles the task of translating and switching voice and fax traffic from a traditional PBX to IP form and back. They are available in either software or hardware form, with the advantage of stand-alone hardware being that, as a small computer and router in its own right, the gateway doesn’t rely on your data network’s processing power. Larger, enterprise-class gateways can handle this switching-and-translating task for up to thousands of voice channels.
