gumstix

HI,
I'm using gumstix for VoIP and thinking to add hardware FXO port,

silabs provide: Si3054 integrated silicon direct access arrangement
(DAA) with an AC-Link interface, compliant with Intel AC 97 2.3
specification

Zaptel/Asterisk support Si3050 and can be ported for Si3054

Any one can helpme with this???

thanks,
Carlos
