We have been using Yeastar products for over 4 years. After so long using Yeastar products, coming across the new P-Series feels like a revolutionary change for our SMB clients. Recently we hosted a P550 in our office for internal use as well as to show the demo to clients inquiring for a phone system. So far whoever we have shown the demo were very impressed because of its simple, easy-to-use management system and at the same time customizable to many extents. The P- Series has helped us getting more recognition in the market.

Yeastar as a company has been an excellent resource providing great support from sales to implementation and troubleshooting, resulting in our resellers and sales team having excellent knowledge of the products and market, and the system itself (Yeastar P-Series) has performed above our expectations. The features are exactly what we were looking for and the support from Yeastar Sales/Presales/Support team members has been exemplary.
