I had a similar problem with a client. I hooked up a butt set to the line
and listened and only heard 4-5 digits being sent. The problem ended up
being high loop current on the line. It should be around 20-25 milliamps,
but this one was 45. High loop current can cause a variety of strange
problems. There is more information on it at www.sandman.com if you want
to look. The easiest way to fix it is to put a 500 or 1k ohm 1 watt
resistor in series with both tip and ring.
