Never ever answer these calls. That merely confirms that you have a working number, and they will increase. I am within an inch of removing the home phone in favor of my cell. Why should I keep paying for something that has become a nuisance rather than a convenience? We still pay a "luxury tax" to the Federal government for using this "luxury." Add to that the cost of a good blocker, which the spammers have long since learned to work around, and it's just no worth the return.
