Can You Block Unwanted Calls?

When the phone rings, you generally want to know who is calling you. Today, caller ID is almost standard in most places, and if not, the answering machine can be used to screen calls if you aren’t sure if you want to talk. Though these things are great, they can’t always stop annoying calls, especially when someone insists on leaving message after message that you don’t want. This might lead you to want to block unwanted calls so that you can have some peace and quiet in your home. If you work from home, this might be something that is very important to you.
