Security alarm company. My husbands company uses them for their chain of restaurants. So if you get a call from them in the middle of the night, pick up - they need to make contact and will try all numbers they have been provided until they reach someone. If they don't reach you or another employee in charge, they call the on call person for the companies executive offices...and no one wants an POed executive chewing them out for not picking up the phone.
