High-speed 4G LTE cellular module providing high-speed 4G data internet failover, VoLTE HD voice, and SMS messaging for Yeastar PBX systems.
Product Overview
The Yeastar 4G LTE Module is a high-performance cellular expansion card engineered to deliver dual-purpose high-speed 4G LTE mobile data and cellular voice communication to Yeastar IP-PBX systems. Supporting 4G LTE, 3G, and 2G fallback, it equips business phone systems with robust 4G data internet backup and cellular voice trunking. When installed, the 4G LTE module can serve as the primary or secondary WAN connection for the PBX, keeping remote Linkus UC clients and SIP trunks alive during wired fiber or broadband outages. Compatible with both Yeastar P-Series (P520, P550, P560, P570) and S-Series PBXs, it includes dual external SMA antenna interfaces for optimal diversity reception.
