Product details
DGW-3002 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, enabling users to configure, maintain, and customize services quickly. It also supports open API interfaces for secondary development and system integration.
DGW-3002 provides 2 software-configurable E1/T1 interfaces, respectively. They support PRI, SS7, and R2 signaling, with maximum concurrent call capacities of 60 channels respectively, meeting the digital trunk access and VoIP interconnection requirements of deployments of different scales.
