How to use Call Waiting
You can have only one active call at any given time, which means that if you receive and accept a new incoming call, the existing call will be put on hold. During a call, the Call Waiting feature (if enabled) will use a beep to announce the second incoming call.
1. To accept an incoming call while already on an existing call, touch the Answer button on your device. The existing call will be put on hold and you will start the new call.
2. To switch back to the original call, touch Swap.
3. To switch to the new call, touch Swap.
