Overview:
VoIP
media gateway is a cost effective and standards-compliant VoIP Media Trunk
Gateway from E1/T1 to Ethernet, which is generally called TG/SG or VoIP Voice
Gateway, designed for enterprise users and ITSP (Internet Telephony Service
Provider) environments. BD-MG900/BD-MG1000 locates on the interface of PSTN and
IP network, providing signaling transformation between SS7, ISDN PRI, R2/CAS,
Q.SIG, V5.2, DPNSS signaling and SIP & H.248 Protocol, as well as media
transfers between the PSTN and IP network.
With
modular design, it’s easily expandable from 1E1/T1 to 52E1/T1.
Application:
● IPCC(IP Call center);
● IP dispatcher;
● Unify communication;
● E1 Trunking port for operators,
traditional switch, IP soft switch and software of IPCC;
