[Asterisk-Dev] Hardware details for the Digium TDM400P

[list at asd-group.com]

Does the TDM400p's FXO mode sound like a high quality device to callers ?

I ask because I've just tried to call Digiums distributors in Australia, in
three different states. They all had the same voice response system, which I
imagine uses Digium hardware/Asterix, and the sound was terrible - low
fidelity and lots of clicks & crackles.
