the scam thing involved dialing 90# ...here is the info:
....someone "received a telephone call from an individual
identifying himself as an AT&T Service Technician that was running a
test on our telephone lines. He stated that to complete the test the
QMOW should touch nine (9), zero (0), pound sign (#) and hang up.
Luckily, the QMOW was suspicious and refused. Upon contacting the
telephone company we were informed that by pushing 90# you end up
giving the individual that called you access to your telephone line
and allows them to place a long distance telephone call, with the
charge appearing on your telephone call. We were further informed
that this scam has been originating from many of the local
jails/prisons. Please "pass the word"."
