The beta release of the W400 board has just been announced. This is our first GSM capable telephony interface board. The W400 board allows IP-PBXs built with Asterisk to communicate with the GSM cellular network. It supports up to four simultaneous quad-band EGSM sessions enabling maximum compatibility worldwide. It includes onboard hardware echo cancellation, noise suppression and DTMF detection. The W400 comes in a PCIe configuration.
