Or maybe you need a moment to prepare for a caller. Now you won't wonder who called while you were away. Your display unit will show and store the time and date of the call, along with the caller's name and telephone number. Connect your Caller ID unit to your telephone or plug in your Caller ID phone. Caller ID units and phones have varying amounts of memory.
Most models delete the first call on the memory list when the calls exceed the memory capacity.
You won't have to keep dialing a busy number over and over. This feature allows you to program your phone to dial a busy telephone number for 30 minutes or until the line is free. Your phone will alert you with a special ring when the called telephone number is free. When you pick up your phone, the called number will start ringing. You will be able to make and receive calls while the feature is trying the telephone number.
