Unfortunately spam callers has become quite popular these days for telemarketing companies lately. If you receive an unwanted call, there are a few different things we recommend doing to stop future calls.

### How Blocked Callers Works

There are two different ways to filter incoming calls with block callers.

* **Challenge** - force the caller to Press 1 to continue and connect the call. This is similar to a web form CAPTCHA to prove they caller is a real person and not an automated system.
* **Block** - calls will be immediately ended with no option to connect the call.

We recommend challenging calls over blocking, its better to allow a call to come through if it's human than get totally blocked.
