VoIP Media Trunk Gateway/E1 to SIP VoIP Gateway is digital VoIP gateway converts signaling/voice media between digital TDM connections and VoIP connections, which brings the cost savings of VoIP to your legacy PBX with the powerful combination of Niceuc VoIP Media Gateway. The gateway acts as a bridge connecting the legacy system through a PRI interface to SIP trunks through your existing internet connection. Niceuc Gateways instantly upgrade a legacy phone system, allowing it to use a SIP trunk out to an ITSP; and connects SIP Trunking to reduce long-term telephony costs by replacing traditional phone lines.
VG Series VoIP media gateway is a cost effective and standards-compliant VoIP Media Trunk Gateway from E1/T1 to Ethernet, which is generally called TG (Trunking Gateway) or SG (Signaling Gateway) or VoIP Voice Gateway, designed for enterprise users and ITSP (Internet Telephony Service Provider) environments.
Three models VG900 / VG916 / VG1000 locate on the interface of PSTN / TDM and IP network, providing signaling transformation between SS7, ISDN PRI, R2/CAS, Q.SIG, V5.2, DPNSS signaling and SIP Protocol, as well as perform the conversion between PSTN / TDM and VoIP SIP.
With modular design, it’s easily expandable from 1 to 52 E1/T1 ports.
