Product details
DGW-3004 is a digital VoIP voice gateway that supports E1/T1 digital trunk interfaces. It enables interconnection between traditional digital telephone lines (PSTN/ISDN) and VoIP networks, allowing seamless integration of legacy telephone networks with IP voice systems. The device provides an intuitive web-based graphical management interface, allowing users to configure, maintain, and customize services quickly. It also supports open API interfaces for secondary development and system integration.
DGW-3004 provides 4 software-configurable E1/T1 interfaces. They support PRI, SS7, and R2 signaling, with a maximum capacity of 120 simultaneous calls per interface, meeting digital trunk access and VoIP interconnection requirements for deployments of different scales.
