ok...so you dialed 7.... 
Then it could have helped if you made it sound from a taperecorder (low quality, EQ cuts under 500Hz or so and above...12kHz or so... then pull up a bit in the mids. And put a "tape rolling" sound, so when he opens the taperecorder, we hear the wheel turning...
Or record it to a tape, and play it from that taperecorder... It takes some time, but worth it I think. You do have to have a bad taperecorder...otherwise it's to clear.
And I want a S virus
