Yeastar TG Series VoIP GSM/3G/4G Gateway

The Yeastar TG Series is a range of VoIP GSM/3G/4G gateways connecting GSM or 3G WCDMA or 4G LTE networks to VoIP network directly and can support two-way communication: GSM/3G/4G to VoIP or VoIP to GSM/3G/4G. It is the best GSM trunking solution for IP-based telephone systems, the best fallback solution in case of landline outages, and also the best alternative for areas with limited landline or SIP connection. It links up PBX systems with mobile networks, helps save phone bills tremendously with mobile-to-mobile calls and SIP trunks, supports sending and receiving SMS messages via web interface and bulk SMS, and acts as a cost-effective backup when the landline network goes down.
