Its biggest benefit is a reduction of the high cost associated with normal long-distance and international phone calls. Through a 10/100BASE-TX Ethernet port, the DVG-1402 connects directly to your company network or the broadband line (DSL or cable modem), without going through any PBX. It provides 2 FXS (Foreign Exchange Station) ports (2 RJ-11 phone sockets) for connection to 2 telephone sets or fax machines.

The Gateway receives voice and data services over a single network connection. You make and receive voice calls over the same line that you use to connect to the Internet, and pay the same Internet connection charge, plus a service charge to your Service Provider.

The Gateway incorporates Quality of Service (QoS) functions to ensure that voice received is almost the same as that received on the ordinary phone.

Other capabilities include echo cancellation, silence suppression/comfort noise generation (when there is a prolonged silence), adaptive jitter buffer and lost voice packet recovery.
