My favorite is the folks who leave an 800 number for you to call back on. If I'm in a particularly pissy mood, I program the voice mail system to call that number, stay offhook for 3 minutes and then repeat the process, all of this done after normal business hours. Let's see, 12 ports all calling that 800 number over and over for 12 hours and staying offhook for 3 minutes...yeah...let's hit their wallet for a change! Oh yeah, I leave 4 ports out of the outdial pattern so I can still take emergency calls!!!
