Last Call Return (*69) provides the phone number of the last person who called—whether or not the call was answered. It also monitors a busy line when you press "1" to return the call.
Lift the receiver and press *69 (or 1169 for rotary phones).
The phone number of the last call received will be announced and you will have the option of returning the call.
If the line is busy, hang up and the line will be monitored for 30 minutes. A short-short-long ring will let you know when the line is free. Once you hear the ring, lift the receiver and the call will be made automatically.
Call Return will monitor a line for 30 minutes. During this time, 5 attempts will be made to signal your line. If after 30 minutes you have not responded to the signals, the request will be cancelled.
