Oki BV1250 Internet Voice Gateways (IVGs) are self-contained H.323 Version 2
compliant communications devices (Gateways) that allow organizations to route
both voice and fax communications over any TCP/IP network.
Oki BV1250 IVGs can be used to seamlessly bridge PSTN, PBX, Key Telephone,
and analog telephone systems with digital data networks, allowing organizations
to more fully exploit their existing intranet and internet facilities. Most
importantly, since communications take place over digital data networks, the high
cost of long distance communications over conventional telephone networks is
virtually eliminated.
In the simplest sense, a BV1250 IVG unit converts outgoing voice or fax signals
into a digital format, compresses and packages the signal for transmission over
digital TCP/IP networks. On the incoming side, the IVG reverses this process,
receiving voice or fax data packets and translating them back into appropriate
voice and fax signals.

communications.
