Yeastar is known for its suite of cloud-based UC solutions. This time, we’re not reviewing one of its cloud-based platforms, however. We looked at Yeastar’s S-Series VoIP PBX, an on-premises modular VoIP PBX that enhances communication with the help of a compact and powerful analog/VoIP capable system.
Its advanced communication features create seamless business communications for small-to-medium-sized enterprises by connecting traditional phone lines, VoIP, and cellular networks. The S-Series is easy to configure and manage, a sort of plug-and-play solution that enables you to control the system from your mobile phone via a Web GUI. Users can even stay up-to-date with email, SMS and voice alert.
What the S-Series PBX offers is scalability, easy installation/management, and exceptional performance. It is geared toward stand-alone telephone systems, all the way to enterprise-class IP telephony services up to 500 users.
What distinguishes Yeastar’s S-Series from other VoIP systems is its ability to integrate with CRMs such as Salesforce, and its simple licensing model. Users gain access to free lifetime software firmware, which is usually an annual fee by others.
