Yeastar S100 is a powerful IP PBX that can control VoIP telephony for 100 users and 30 concurrent calls. Using a modular design, the S100 lets you choose what ports you get, so the PBX will match the needs of your particular deployment. It works like this: the S100 has space for two expansion boards. There are two options for expansion boards. The EX30 Expansion Board gives you one E1/T1/PRI port for digital telephony. The EX08 Expansion Board has eight RJ11 ports and four module slots. For each EX08 board you install, you can add four of the following modules:

• S2 Module: 2 FXS Ports
• O2 Module: 2 FXO Ports
• SO Module: 1 FXS Port & 1 FXO Port
• B2 Module: 2 BRI Ports
• GSM Module: 1 GSM Channel
• 3G Module: 1 WCDMA Channel
• 4G LTE Module: 1 3G/4G Voice Call & Data

Note that the S100 only has six antenna sockets, so you can install a maximum of six GSM, 3G, or 4G LTE cellular modules across the two expansion boards.

The modular nature of the S100 goes further: you can also install one D30 Module to expand the number of users and calls that the IP PBX can control. The D30 Module gives you control for 100 more users and 30 more concurrent calls.

Yeastar S100 uses an industrial-grade quad core Freescale chip with Texas Instruments DSP (digital signal processor) and dual Gigabit Ethernet ports to provide fast, clear communications. The Yeastar VoIP phone system includes extensive PBX support for functions like video calls, voicemail to email, one-touch recording, caller ID, automated attendant, and many more. Using the TLS and SRTP transport protocols and the integrated internal firewall, you can secure your communications, even as you bring mobile users into your office's phone system using the Linkus Mobile Client for Android and iOS. S100 is 1U rack-mountable.
