Combine four FXO/FXS modules, an A400P card, and a net5501 or ALIX 1 with Asterisk to build an IP-PBX/Voicemail system with extraordinary flexibility.
The FXO module allows you to connect an analogue handset, fax machine, alarm system or other internal extension to your VoIP phone system.
Perfect if you’re upgrading from an analogue telephone system to digital and you have existing incoming analogue lines you’d like to connect.
