Don't you find the telephone ringing annoying?
For a number of years, we kept the ringer off on our phone. The only notification we had of a phone call was the quiet click of the answering machine. If someone thought their call was important enough to leave a message, we would eventually hear their voice.

In the last couple of years, we've got a new phone number which for some reason doesn't get many sales calls, and our friends only call us at home if it's important. So we've been able to leave the ringer on these days and still have peace.
