Picked this off another forum:

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.

DO NOT press 90# for ANYONE.
