Yeastar 4G Wireless S-Series VoIP PBX is Now Available

4G LTE, as the fourth generation of mobile networks, aims to offer users faster, more reliable mobile broadband internet for devices like smartphones, tablets and laptops, enabling users to access mobile data at far higher download speeds than previously available. With the new terminal devices (smartphones, tablets, etc.) and other new applications, the demands on the mobile broadband network are rising. Especially in some urban area or countries with island structure, where the physical trunks are hard to build up, the development of mobile services becomes highly significant. Lots of operators are aggressively expanding their 4G offerings in recent years which brings more and more LTE subscribers in the world.

To go with the global trend of 4G LTE services and meet higher communication demands from customers, Yeastar has added support for 4G LTE on S-Series VoIP PBX with 4G LTE Module, and we are proud to announce that the 4G LTE Module is now available. With four models to choose from, the 4G wireless S-Series VoIP PBX is the ideal system for business needs of temporary locations, mobile offices, and places where a fixed-line broadband is not available. Learn more about 4G LTE Module.

SIP Trunk over 4G LTE

Yeastar enables 4G cellular data on SIM card with 4G LTE Module, making the 4G LTE become the primary internet connection for S-Series VoIP PBX. Supporting 3G/4G network standard and high speed data transmission, the 4G capable S-Series VoIP PBX can register SIP trunks and make SIP calls with built-in data. VoLTE is also possible with carrier support.

Benefits

Providing 4G LTE network failover for business continuity

Automatically reroute the S-Series PBX’s internet usage to the cost-effective 4G LTE wireless network and provide businesses with an essential internet continuity option when the PBX’s primary internet connection fails. With 4G LTE failover, SIP trunks are even more resilient.
