I got this info from a friend..thought I'd pass it on...just in case
---Be advised a "new" telephone scam has been taking place. The way the scam works is outlined below. Pass this information on to everyone you know.
I received a telephone call last evening from an individual identifying himself as an AT&T Service technician who was conducting a test on telephone lines. He stated that to complete the test I should touch nine(9), zero(0), the pound sign (#), and then hang up.
Luckily, I was suspicious and refused. Upon
contacting the telephone company, I was informed that by pushing 90#, you give the requesting individual full access to your telephone line, which enables them to place long distance calls billed to your home phone number. I was further informed that this scam has been originated from many local jails/prisons.
I have also verified this information with UCB Telecom,Pacific Bell, MCI,Bell Atlantic and GTE. Please beware DO NOT press 90# for ANYONE
