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 dialed 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 dialed, but on most phones, the redial button provides quick access to the last number dialed.
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 dialed will appear as the phone redials the number.
