I can't think of a title for this one

For some time we've been having phone problems. It seems that calls weren't being recorded, messages weren't getting through etc etc. So today I bought some new technology to try and fix the problem. Rang the home number to test it.....

"What is the mass of Jupiter?"

Strange. Rang off and tried again.....

"What is the population of China?"

Checked the box. Turns out we had bought a question machine by mistake.
