Prodcut Introduction

Etross BD400G/800G cards support up to 4/8 GSM channels and enables users to access the mobile network with their existing asterisk,freeswitch, yate and others.

Our GSM card simulates the FXO module and acting as a FXO channel, so it can be used the same as FXO card. So any X*2 FXO/FXS, Y GSM ports can be combined if X+y=4 or 8 for GSM400G/800G.

It's more than a GSM card. FXO/FXS can be inserted into the slot to be the hybrid FXO/FXS/GSM cards. BD400G/BD800G have 4/8 slots respectively. Each slot can be inserted with GSM or Single/Dual FXO/FXS modules.
