Multi-SIM VoIP to GSM/3G Gateway 


With ever increasing mobile call traffic and expanding field forces, organizations are realizing the need of GSM trunking for cutting down the cost of mobile calls. GSM voice extends business reach where fixed lines cannot reach and saves telecom cost by converting fixed-to-mobile calls into mobile-to-mobile calls.

Matrix SETU VG is a compact VoIP-GSM gateway with up to 4/8 GSM and 3G SIM support. Integrated GSM/3G connectivity and open standard SIP support enables SETU VG gateway to easily connect with leading IP phone systems, software based IP-PBXs, hosted and SIP trunking services. SETU VG is a suitable GSM trunking solution for enterprises, call terminators and areas with limited landline and internet connectivity such as remote project offices, rural and educational institutions.

Hop Off GSM Trunking for Multi-Site Organizations

Multi-location organizations while communicating with dispersed field forces incur huge telephony bills using PSTN services. Instead, routing of long-distance calls across IP and dropping them off to the GSM network at remote GSM gateway saves VoIP-PSTN inter-connection costs significantly.

Users located at main office can access the GSM trunk of SETU VG gateway and transparently hop off to the PSTN to reach off-net locations.
