I used something similar to let my computer pickup the phone when I
wanted to login from the office: the computer would pick up the phone
when a SINGLE ring would be followed by another ring after 15-30 sec.
This will hardly ever happen by accident, and is also easily
recognised by human beings. The 15-30 seconds was just enough to
redial the number on an old fashioned rotary dial.
