Yeastar TG800L 8-Channel LTE VoIP Gateway

The TG800L connects any SIP-based phone system to the mobile network through 8 independent 4G LTE channels, letting businesses route calls to and from mobile numbers without paying carrier termination rates on every call. It works with Yeastar systems as well as any standard SIP server, softswitch, or IP-PBX, including Grandstream and Elastix deployments.

Each of the 8 channels runs its own SIM, so it's built for businesses making a high volume of calls to mobile numbers, such as customer service teams or delivery/logistics operations running promotions and updates to customers on mobile lines. Configuration is handled through a web interface, with support for call routing rules, blacklisting, call detail records, and mobile port grouping.

It supports the full range of standard VoIP codecs and transport protocols, along with network security features like IP blacklisting and attack alerts, so it can sit safely on a business network without extra hardening.
