INFORMATION

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.
