Hello,

Is there a way to prevent the 90# scam in our pbx. For those not familiar here is the scam:

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 originating from many local
>jails/prisons. I have also verified this information with UCB
>Telecom,Pacific Bell, MCI, BellAtlantic and GTE. Please beware.
>
>DO NOT press 90# for ANYONE.
