Summary
GOIP GSM Modem Gateway bridges the GSM services and the IP networks. It is ideal for VoIP to GSM services where a fixed telephone line (PSTN) is not available or for cell phone roaming via the VoIP network. GOIP Modem GSM Gateway is designed to work in conjunction with key phone systems and IP-PBX to provide GSM communications. The extensive compatibility of the GOIP makes it an ideal choice to be deployed in multi-vendor open architecture VoIP networks. GOIP GSM Gateway is a great way to provide fast phone service deployment where regular PSTN line may not be readily available. GOIP GSM gateway also provides significant savings in usage (long distance or international), infrastructure and maintenance cost compared to conventional PSTN.
