Yeastar

Yeastar TG Series Gateways connect GSM networks to VoIP networks to provide two-way communication: GSM to VoIP and VoIP to GSM.This allows you to connect most IP-based telephone systems including Yeastar IP Phone Systems, and softswitches to a GSM network; which can provide a sophisticated fallback solution when landlines go down, or be used to increase call traffic capacity by providing additional dial-tone.
