What irritates me are the calls after 8PM at night. With children who go to bed at 8PM during the school year, phone calls really upset us. Our son is a really light sleeper and unless we turn off the phone in our bedroom, the ringing wakes him up. My dh has gotten to where he'll answer the phone on speaker phone and I'll start crying REALLY LOUD like a baby. He tells them that they just woke up the baby and now he'll be up another hour trying to get me to sleep. They always apologize and apologize as he tells them to remove him from their list. It usually works. We always laugh about it. (I guess we are easily entertained.)
