Can anyone tell me how much better a telephony board really is over a good voice modem? My relatively old Zoom modem (sorry, don't have the exact model on hand) delivers terrible voice quality. However, I'm a little skeptical about a $300 device being that much better.
Has anyone actually tried a Telephony card and seen the difference?
Can they produce voice as good as any person talking on the phone? (That's where I'd put the bar for $300)
In particular, I'd really like to hear from anyone who's used the telephony board that NCH recommends:

It's probably the one I'd get. Since they recommend it.
Thanks
