So you missed what might have been an important telephone call to a land-line phone with no redial button and no caller ID. You want that phone number. Even if the available phone is an antique with a rotary dial, your chances of getting the number are good. In the 1960s and 1970s, AT&T developed a set of codes to engage special telephone services. Those codes became a recognized standard still used today. "Identify Last Incoming Call" was one of those services.
Get a dial tone on the telephone line on which you want the number of the last incoming phone call.
Press "*69" (or dial "1169" on a rotary phone).
Listen for and record the number of the last incoming call. If you do not hear a voice providing that number (and it is not automatically redialed), go to Step 4.
Contact the land-line service provider. At your location, a per-use option may not be available, or the "Identify Last Incoming Call" code may differ from "*69."
Things You'll Need

If you are likely to want last-incoming-number information three or more times a month, inquire about the monthly rate with your land-line service provider. Rates start at $1.50 per month. Telephone companies charge the per-use fee at the time of delivery of an automated message.
In California, telephone number announcement is not allowed. Pressing “*69” dials the number immediately, without its being announced by a voice.
In some states, land-line service providers charge a fee just for disseminating the information that the last incoming call was private.
An automated voice announcement may offer the option of having the number of the last incoming call automatically dialed. The phone company may charge a fee for this service.
If the number is outside of the network of the land-line provider, you will probably receive only that information.
