Supported Model: S20, S50, S100, S300, P550, P560, P570
The Yeastar S-series & P-series have a modular structure. Depending on your requirements, a composition can be made with the available modules (FXS, FXO, ISDN2, GSM/3G). In the S20 two modules can be placed as standard and in the S50 even 4. The S100 and S300 do not have a standard place for modules, but with the use of an extension module this is still possible. You will then even have access to an E1/T1/PRI port. The S100 has room for 2 expansion modules and the S300 even has room for 3 expansion modules.
