The user called into to retrieve messages, and played back this caller's message. The '4' DTMF digit was played (as it was happily recorded). It echoed back weakly (side tone, or analog hybrid, or for whatever reason there was a small amount of echo back, like there is in the real world). As '4' was the 'delete' message, the echoed back DTMF was detected and acted on. The message deleted itself! This was not an isolated incident, it occurred rarely, but frequently enough to become a real problem. As you can imagine, it wasn't easy to figure out what the actual problem was, as for all reasonable checks it showed that the caller pressed 4. _______________________________________________ "This message will self-destruct in 15 seconds.
