- One thing that I found difficult to use about Call Waiting is
- the way that a user is informed of another call. Currently,
- this is done by the exchange sending a special tone but the
- problem is the user might miss the tone especially if it is too
- soft. I am wondering, what if the phones are themselves modified
- with flash detector circuit. I propose a detector that looks for
- three consecutive circuit breaks (flash or recall), these breaks
- are of very short interval, should be even shorter then
- what the recall button generates. By waiting for three breaks from
- the exchange, the detector won't confuse that with the user pressing
- the recall button. Having detected the three breaks, an LED would light
- up to indicate CW. I think having a detector to detect the tone
- would make the phones far too expensive and hence my alternative
- proposal.

- Any comments ?
