You can use your landline telephone to determine the number of the last call made from that phone. This may prove beneficial if you misplaced someone's phone number, to check if you dialled a wrong number or if you suspect undesired activity regarding how your telephone has been used to contact others. Certain telephones may have their own way of storing numbers dialled, but on most phones, the redial button provides quick access to the last number dialled.
Locate the "Redial" button on the landline telephone. This button appears in different places on each phone model, but many redial buttons are located on the phone's base.
Pick up the receiver on the landline telephone. Press the "Redial" button.
Look at the display screen on the telephone base or on the telephone itself, depending on its location on your model. The last number dialled will appear as the phone redials the number.
If your phone does not have a display screen, you might have to wait until someone picks up the phone or you reach an answering machine detailing a personal residence or business to know the identity of the number called. If you want to know the exact number, and not just the name of the recipient, ask the individual for the number or leave your name and number on the answering machine requesting the phone number.
In some cases, you might not want to actually make a connection when you redial the number. If so, hang up the phone as soon as the full number appears on the screen to prevent someone on the other end from picking up the phone and talking to you.
