Avoid Unwanted Calls

One of my pet peeves is answering the phone and finding out that the person at the other end of the line is a telemarketer selling a product or service that I don't need. Some telemarketing persons simply don't know the proper time of calling. It's annoying when they call early in the morning especially during weekends. After a long week of work, people normally look forward to a relaxing weekend. It's a time when there's no pressure to wake up early for work. Imagine being awaken by urgent ringing of the phone only to find out that it's a sales person asking you to patronize their product or service. That kind of disturbance will surely ruin a person's day. It's often hard to avoid these calls because the numbers used are unknown. It would be a big advantage to be able to lookup by phone number. That way you can avoid unwanted calls.
