How do I use call waiting?
If you are on a phone call and you receive a second phone call, you can keep both calls live. To do so, press the off-hook switch, which will answer the incoming call, and put the existing call on hold. To switch back to the original call and put the new call on hold, simply press the off-hook switch again. At any time, you can press the on-hook switch, which will hang up the current call, and return you to the call that is on hold.
