The call-waiting feature on a phone allows you to answer another call while you’re on the line with someone else. The original call is placed on hold, while the new incoming call is answered. This is feature is prominent on many cell phones, and it makes it easier not to miss important calls. Although call waiting is a useful feature, there may come a time when you do not want to have call waiting active. For example, if you are expecting an important call and do not want to be interrupted, you may decide to disable the call-waiting feature on your cell phone. Warnings Writer Bio
