Can you dial on a rotary phone with a cell phone?
Remove the dial from the body of the phone. It should have two pairs of wires attached. One acts like a switch: it's 'OFF' if the dial is in the resting position, and 'ON' if the dial is moving. The second pair gives a pulse based on the number dialed.
What equipment do I need to convert a rotary phone to beeps?
Oh, and by the way, its called a rotary phone. "Dial-up" refers to the modems used to connect to the internet before cable and DSL. It was called such because it connected by the phone lines. 0. tecno geek Andrew546. Reply 13 years ago on Introduction.

How do you charge a cordless rotary phone?
Pulse-to-tone converter – This converts the dial pulses of a rotary phone to touch tones. You don’t necessarily need one (the XLink devices are already able to recognize pulse dialing), but you might want one to use a rotary phone with a cable-based phone service or VoIP line. Since rotary phones only have 1 through 0 on the dial, some of these ...

When did rotary phones stop being used?
Phasing Out Rotary Dial Until the 1970's, when push button tone dial was introduced, rotary phones were the only viable option for user controlled phones. By the 1980's most rotary phones were phased out. In many areas it is now an added feature to have rotary service.
When did rotary phones become obsolete?
The rotary dial phone was once the be all and end all of the telephones. Like the cellphone of today, everybody had one, and they ruled domestic communications for decades. But that all changed in the 1980s when they were supplanted by a new upstart, push-button telephones.02-Jun-2021

How do I connect my old landline phone?
How to Set Up LandlinesPlug one end of the telephone cable into the appropriate port on the base of your landline phone. ... Plug the other end of the telephone cable into the appropriate wall outlet. ... Insert the appropriate end of you phone's DC power adapter into the appropriate port on the base of your landline phone.
Step 1: Open the Phone
This one had a single screw holding the plastic in place. Just get it opened enough to be able to touch the wires; we'll leave most of it intact.
Step 4: Take It All Apart
Since we'll be taking this whole thing apart and sticking it into an Arduino, you disassemble it down to individual components.
Step 6: Attach It to Your Microcontroller
I'm using a Teensy 3.0, but you can pretty much use any input-output microcontroller.
Step 7: Read the Values
You can find my code for reading the dial numbers to serial here: https://github.com/agentcupcake/rotary-hack/blob/master/dial_reader
Step 8: Attach It to Something!
You have an input device! What will you connect it to? Add some LEDs. Make it change the speed of a motor. Make it dial your cell phone. Re-attach it to the phone and have it choose music to play through the headset.

Oh my god, this is PERFECT! I was having so much trouble trying to figure out where and how to connect the wires of the dial, and here you are with this elegant solution! Thank you so much for sharing this, you saved me a ton of work. Kudos!!
Step 1: Cutting
cut the male end off of a modern day phone cord. its really blurry cuz of the close up.
Step 2: Wiring It Up
attach the wires as shown below (red-red yellow-yellow green-green) and leave the black one hanging, its not needed.
Step 4: Plug-it-in
plug in the male modern jack into to the wall jack, pick up the phone and it should work.
Step 1: Just a Bit of Theory
The rotary phone used to release the line for a fraction of seconds 1 to 10 times to dial a digit. The whole system was working without any silicon, with only relays and electromechanical components.
Step 2: Technologic Choices
I choose to use DECT analog cordless phones for this project as they are really common and not expensive. This project should also work with an old analog cordless phone as well.
Step 3: Circuit Design
The circuit is basically an interface between a cordless handset and the rotary phone’s hardware. The functions it carries out are:
Step 4: Software
Beside dialing using Roman Black’s DTMF algorithm (tut13), the software is in charge of power management shutdown, hang-up detection, dial reading, ring detection,…
Step 5: PCB Design
PCB is two layers. I draw it using DIP Trace. Feel free to use the Gerber files to make your own. I did it with through-hole component for easier DIY soldering, except for 2 chips that don’t exist in DIP package. But with flux, small tip and patience, it is possible to solder it with an iron.
Step 9: How to Choose the Cordless Phone
The design is done to be as universal as possible and should work with the majority of DECT cordless phone as long as they have the following specifications:
Step 18: Putting It All Together
When all tests and settings are done, power OFF the phone and unplug the cordless handset.
The Phone
The device in question is a NT analog phone, based on the classic Western Electric model 500. The models are very similar with only minor differences, for example the printing of the numbers on the dial is slightly different for models from Canada.
Pulse Dialling
Pulse dialing is very simple as it is derived from the mechanical rotation of the dial. As it turns from the dialed digit back to the resting position it toggles the local loop voltage to transmit the data to the FXO.
DTMF Dialling
DTMF on the other hand is an in-band signalling method using eight different frequencies transmitted in pairs. To use the example from Wikipedia, to transmit a ‘1’ on a DTMF system it will transmit two tones, 1209Hz and 695Hz together:
Converting signalling
So, the first piece of equipment I needed was a pulse-tone converter. Indeed, such a device does exist to convert the ‘ticks’ produced by the rotary dial to the ‘beeps’ produced by most keypad phones. I was a little squeamish about tearing apart a working antique, so I opted to buy an external dial tone converter box from OldPhoneWorks.
The SIP ATA box
There are heaps of Analog Telephone Adapter (ATA) boxes on the market, but in the interest of keeping this project low-cost I opted to purchase a new-old-stock Linksys PAP2T-NA device from eBay.
Making calls
That night, I successfully ordered a pizza using an antique phone. Dialing was laborious, but novel for somebody my age, and honestly kind of fun.
