Telephony Cards

 

This section features telephony interface cards from Sangoma, Digium and Openvox. Telephony cards allow the software PBX to interface with a variety of phycial interfaces available for traditional phone systems such as FXO, FXS, T1/E1, ISDN PRI, ISDN BRI, GSM, etc. These cards are typically designed to fit into a PCI or PCI Express port on the  motherboard of the computer in which the phone system is being installed. Some cards can work with native drivers built into the phone system software being used while others may require additional software to integrate the physical card with the software phone system.
