hi;
if i have this correct;

T = Tone Dial


Qn = Q0 Result codes displayed
Q1 Result codes suppressed (quiet mode)
Q2 Quiet in answer mode only

Vn = V0 Numeric mode
V1 Verbal mode

hn = H0 Hang up (go on hook)-Default
H1 Go off hook

....so, we end up with;

Tone Dial, Result codes displayed, Verbal mode, Hang up (go on hook)

Not sure how that helps :-(
