Scalable GSM/3G to VoIP Gateway


ETERNITY GE12S is a gateway scalable up to 40 GSM/3G channels. The gateway interconnects to an IP-PBX over LAN/WAN interface. The gateway helps avoiding the interconnections cost by placing calls to mobile numbers over the GSM/3G networks.

Automated routing algorithms help taking advantage of various service provider schemes based on time, number or the network called.

Organizations can take advantage of corporate CUG plans for making frequent calls to field workers from office. Call centers, banking and financial institutions can take advantage of the GSM/3G connectivity while making calls to the mobile numbers of customers, employees and other business alliances. A completely non-blocking architecture makes ETERNITY an ideal platform for those offering termination services.
