Call Waiting ID - FiOS Digital Voice Call Waiting ID works in conjunction with Caller ID and alerts you to an incoming call when you are already talking on your telephone. Call Waiting ID may also show you the name or the number of the person calling you. You can then choose to continue your call or answer the new call.
Call Waiting ID requires Caller ID and Call Waiting, as well as a special display device (purchased separately) that supports Caller ID and Call Waiting.
