Hi, Has anyone used Sangoma USB FXO with FreeSWITCH?. If yes, could you please let me know if it works properly? I plan to use this to run FreeSWITCH on my laptop and connect to PSTN using this card. Here is the link to Sangoma USB FXO - http://www.sangoma.com/products/hardware_products/analog_telephony/usb_fxo.h... Thanks, Pankaj
