8 Channel GSM Gateway SIP VOIP GP4 1350g 3 lb 12 Vdc 2000 mA Adapter
OFS-GP8
Descreiption
A VoIP GSM gateway (GP) is an IP-based device that enables inbound and outbound VoIP and GSM cellular calls. It is a great alternative to PSTN, especially in area where GSM service is available for VoIP call termination. A typical set up is shown as follow:
GP is designed to work in conjunction with key phone systems and IP-PBX to provide GSM communications. The extensive compatibility of the GP makes it an ideal choice to be deployed in multi-vendor open architecture VoIP networks. GP is a great way to provide fast phone service deployment where regular PSTN line may not be readily available. GSM gateway also provides significant savings in usage, infrastructure and maintenance cost compared to conventional PSTN.
