DAG series is a versatile IP-based voice and fax gateway, it is highly integrated router, NAT, DHCP server, phone gateway functionality. Market-leading voice quality, rich functionality, and lightweight, compact design. DAG series is fully compatible with SIP industry standard, can be achieved with many other SIP compliant devices and software interoperability. In addition, it supports including G.711A / U, G.723.1 and G.729AB voice codec.

Carrier and enterprise-class devices, both low-cost VoIP service while preserving the traditional PSTN network. Especially for new VoIP and traditional PSTN operators to seize market operators.

DAG series can be with the mainstream SIP proxy server(such as Asterisk, SIP registration server, etc. ) to implement  docking. In this kind of environment, SIP server processing SIP registration and call control, DAG series access gateway can realize flow media conversion between the IP and PSTN.
