It looks like audio is going over one of several usb serial interfaces. For 
the Freerunner's GSM interface we would use chan_alsa, but it might need 
modification to treat left and right as separate interfaces if you want to use 
the handset mic and earpiece. There would also be some script glue between FSO 
and asterisk for call handling.
