Ordinarily it should suffice to leave it ambiguous, since ambiguity favors the defense (reasonable doubt). I imagine that it is tempting to the defense to go further and disambiguate, but one can not predict exactly what will happen in response to questions by potentially hostile witnesses, and the witness could spontaneously offer up more detail damaging to the defendant in his or her answer, and the defense would minimize that by minimizing the amount of questioning to only that which is strictly necessary to ensure reasonable doubt.

How many phone calls are we going to listen too.
Ah. That sounds logical. Thanks for the insight.
