Call Waiting allows you to be notified when someone is trying to call you while you are on the phone. With call waiting, you no longer miss important calls.

Call waiting alerts the user of an incomming call while participating in another call, and allows the user to switch back and forth. This is most common on a single line telephone in residential or small business settings, as a multi-line phone system provides the same functionality and more.

When the phone is being used and a second call comes in, the user hears a beep alerting them to the new call. The user can ignore the call, or switch over to it. In most cases, the user would hit the Flash button, or very quickly press and release the on-hook switch. This will switch to the new call, leaving the original caller on hold. since VoIP includes Call Waiting Caller ID, the second caller's phone number will be displayed on your compatible phone.
