OpenVox launches the DGW-300X series, high-performance VoIP gateways
The new DGW-300X range offers robust, scalable E1/T1/PRI gateways compatible with leading IP PBXs.
Flexible scalability for every type of business
The DGW-3001, DGW-3002 and DGW-3004 models offer 1, 2 or 4 E1/T1/PRI ports, respectively, each with a backup bypass port. They support up to 30, 60 or 120 simultaneous calls. All models include two redundant power supplies, two 1 GbE RJ45 ports and one 1 GbE SFP port.
Superior performance for telephony convergence
The gateways support PRI, SS7 and R2 signaling, including R2 variants for 24 countries. They offer a wide range of codecs (G.711, G.723.1, G.729, iLBC, OPUS, AMR, AMR‑WB), as well as T.38 relay and fax pass‑through mode.
Intuitive management and smart operations
A web interface enables service configuration, maintenance and customization. Open API support, auto-configuration, IPv4/IPv6, DHCP, QoS, DNS SRV and integration with PBXs such as Asterisk, 3CX or FreeSWITCH simplify operations.
Carrier-grade reliability
Redundant power supplies and bypass ports ensure service continuity even in the event of a failure. Web management, SNMP, TR‑069, TR‑369, detailed logs and browser-based packet capture facilitate remote support.
