Unique Modular Design for a Future-proof System

Unlike most of hardware PBX systems, Yeastar S-Series VoIP PBX is an innovation designed to be customizable and scalable in nature. With a unique modular design, the powerful system allows you to customize your own PBX system with a flexible combination of telephony interfaces. When your business grows, adding more users and concurrent calls is also possible with S100 and S300 models. The system’s exceptional flexibility and future-scalability have differentiated itself from its brethren in the market and deliver a future-proof solution.

We like Yeastar very much. Mostly because it is modular based. This is much better than other PBX brands which do not allow to improve system with modules/cards.

– Albert Diaz, President at 3NG Networks

Yeastar system is scalable and can certainly meet the evolving needs of the verticals (hospitality) I represent. It eliminates the pots lines and allows my clients more choices when selecting phone service and saving a great deal of money, allowing them to focus more on their business.

Enterprise-grade Feature Set and VoIP Solution

Built from the ground-up for real-world performance, S-Series VoIP PBX comes packed with enterprise-grade telephony features to deliver smarter, better and easier communications experience. Ranging from basic calling functionality to advanced business features like IVR, Auto Provisioning and Linkus softphone, the robust feature set can meet the full spectrum of business requirement.

Successful cases abound. One of our valued partners, NP Networks, has deployed a Yeastar project for his customer and they’re quite impressive. The project involves two Yeastar S300 VoIP PBXs and is crafted for a corporation of 6 dispersed offices, one in the USA and 5 in Mexico. The two S300 deployed have successfully interconnected the 6 offices and streamlined the inter-office communication and call operation. In addition, a full failover solution was also implemented with the advanced Hot Standby feature of S-Series VoIP PBX to help prevent the unnecessary business loss caused by unexpected server failure.

I tested the failover and it is working great! It takes like 5 minutes for the secondary unit to start providing services, but it works pretty good!

I have been working with Yeastar for a long time, but I never created a configuration like this…my customer is very impressed with the reliability of the S300, I replaced his old Elastix PBX with this one. My customer is very happy, they are using Cisco phones and they are working pretty good with the system.

Cost-effective All-IP System with the Ease of Use

I feel that Yeastar system is the next big thing for my segment as we distance ourselves from PBX systems of old and migrate toward IP based technologybeing able to offer a client a metered sip trunk with a 15 concurrent call path billed at only a per-minute charge can cut my client’s phone bill inhalf.
