Digium AEX2430B is a modular telephony card that connects analog station devices to Asterisk-based IP phone systems. This model combines an AEX2400 base card with three S400M FXS modules. The card is a cost-effective and scalable solution for reducing infrastructure like gateways, while integrating analog phones with your VoIP system.
Digium AEX2400 is a base card with room for six FXO/FXS modules in total, so you can add further FXO or FXS port modules to customize the card to fit your phone system. It is a full-length PCI Express card. Digium S400M is a quad FXS module that provides four station line interfaces to connect to analog devices.
Digium AEX2430B comes with a 5-year manufacturer warranty.
