Is there any way for me to connect 2 Rotary phones and when a specific number is dialed, Connect to the second phone. I also am unable to decode the telephone's pulses without directly connecting the dial to the arduino. Sorry if this is dumb, I am new to arduino.
And what do you want to do when the phones are connected? Telephones in the US, anyway require 48 volts to operate properly.
I did, most of those are audio recordings. i want the phones to communicate with one another.
At this point I would suggest that you look at the telephone exchange videos on a YouTube channel called "look mum no computer"
You could use the Arduino to count the pulses and then connect the phones via relay or similar. But telephone exchanges are complex
I watch that channel's telephone videos already. and I dont know how to count the pulses without directly connecting the dial.
without using a ringer, you can use 5 volts
As pointed out, normally telephones have a certain voltage and impedance available on the lines.
The dial switch is the same as the hook, it just disconnects the telephone, in effect, so you can detect dial pulses by watching for an interruptions of the loop current.
You'll have to create the loop current, somehow, and catch the dialed number and decide to connect the two telephones.
Easier: just disconnect the dial and interface directly with the Arduino. The only thing you'll miss is, well, what would you miss? You can hear the dial pulses if your ear is on the handset whilst dialing, so you could probably inject that onto the line.
But see now it gets more deeper - are you planning to synthesize the dial tone, the ring feedback and so forth?
Or is everyone using this gonna be just too young to spot the inevitable infidelities of your simulation?

You may find something here that you can use. It is an intercom using two rotary phones: Intercom using two old dial telephones
I was planning to create a fake dial tone. However for ringing I could use the link 6v6gt mentioned
The reason I want the dial to continue being connected is because I want everything to go through one line.
