I just read a (feb 2003) recomendation for a 'US Robotics 2976' as it is a
new model hardware PCI modem with full duplex.   What model do you have?
(I`m wondering if USR have improved voice quality)

There has been disussion on this list about linmodems in full duplex (too
hard/not done) but not about full duplex hardware PCI modems.   There is an
asterisk half duplex h/w-modem channel as I remember at the moment.
