Fixed VoIP to GSM/3G-ISDN BRI Gateway



SETU VGB is an integrated gateway offering connectivity to IP, GSM/3G and ISDN BRI networks on a single platform. The gateway offers access to IP and GSM/3G networks for existing users of ISDN PBX. For an IP-PBX, it provides BRI and GSM/3G trunks connectivity. The gateway offers 8 VoIP channels, 4 GSM/3G SIMs and 2 ISDN BRI ports.

SETU VGB can also be used to setup IP connectivity between multi-locational offices to take advantage of low cost VoIP calling. Apart from providing voice services, SETU VGB also offers high speed data accessibility over UMTS/HSPA/EDGE data networks. Selective call routing over the fixed, IP or wireless networks as per the programmed least cost routing algorithm, brings significant cost savings and quick returns on investment.

The gateway serves as an ideal solution for SMBs, large enterprises, VoIP service providers and system integrators to offer smooth migration alternative to  IP telephony from legacy ISDN BRI and GSM/3G networks. Further, simultaneous voice and data accessibility over wireless network makes SETU VGB an ideal solution for remote locations with limited fixed line connectivity.
