Yeastar PBX S100 100 Users 30 Concurrent Calls Modular

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 (analog) O2 Module: 2 FXO (analog) SO Module: 1 FXS / 1FXO (analog) B2 Module: 2 BRI (digital) GSM Module: 1 GSM (cellular) 3G Module: 1 UMTS (cellular) Note that the S100 only has six antenna sockets, so you can install a maximum of six GSM/3G cellular modules across the two expansion boards.
