Yeastar TG800 Series VoIP GSM Gateway Unboxing
Yeastar TG Series VoIP GSM Gateways connect GSM or WCDMA or 4G LTE to VoIP networks to provide two-way communication:
GSM/3G/4G to VoIP and VoIP to GSM/3G/4G.
This allows you to connect most IP-based telephone systems including Yeastar IP Phone Systems, and softswitches to a GSM or 3G WCDMA or 4G LTE; which can provide a sophisticated fallback solution when landlines go down, or be used to increase call traffic capacity by providing additional dial-tone.
