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 NC-MG900 / NC-MG916 / NC-MG1000 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.


NC-MG900-208: it is NC-MG900 that has two E1 cards with 8 E1 /T1 ports.

·Signaling support:

-SS7 (ITU-T Q.700 series), 24 bits/14 bits PC, ISUP/TUP;
