IDM IAD04 2-Port Voice Gateway

The IDM IAD04 is developed based on the latest IP telephony technology and Layer 2 Ethernet switching technology, utilizing a MIPS 4KEC microprocessor and a System-on-Chip (SOC) integrating DSP, CODEC, and SLIC. It supports SIP (IMS-compatible) protocol, providing 4*10/100Mbps and 2*POTS interfaces. The product features high integration, flexible networking, excellent interoperability, rich interfaces, strong protocol scalability, and high cost-effectiveness. It can be widely applied in telecommunications carriers, SOHO, and residential scenarios.
