hi, i got problem with my tdm400, sometime when i dial out, it will say “Were sorry you must first dial a one when calling this number will you please hang up and try your call again”, but sometime it doesn’t, i’m currently with AT&T with plan ALL DISTANCE, it work flawless when i plug phone line directly to the wall, with dial the same number, no problem, so i know is not the phone or the line, i think maybe is the txgain,rxgain, i try to change it to see if it work, it didn’t help.
here my setting for asterisk 1.6.0.22
