I remember being on site at a customer site some years ago, running some obscure DOS E-mail app which issued similar beeps which were difficult to disable.
This particular installation divided users up into many small groups of about 4 to 6 users, each group bearing the name or number of the cubicle the users were sat in. Every time a global E-mail went out it propagated around the office in alphabetical order by user group name - which meant a 10 second wave of beeps spreading linearly around the building from one end to the other.
Biting the hand that feeds IT
