No it doesn't and this is not a 1 or 0 problem. What it is..is tone twisting. The CO is not "hearing" the tones properly coming out of the SBX so the call cannot go through and the recording you hear is not reflecting the true cause of the misdial. You need to measure the loop current of the troubled lines and compare it to the one good one..there is a difference somewhere. Compare the polarity of all three lines. Also still perform a digit grab test as well. I am curious as to what kind of equipment generates these lines.
