If someone was calling you, you learned to recognize your "ring pattern" and only answer the phone if the call was for you, not someone else on the party line.
Urban party lines could have 2 to 10 parties sharing a single line. Rural party lines sometimes had even more.
Usually only businesses and professionals (e.g. doctors and lawyers) could afford the extra charges for having a dedicated single party line.
Well it was kind of hard to use because you could only ring for 35 min (because the first ever invented phone you couldn't text) then you had to charge it for 10 hours. The person who invented the first ever cell phone was Dr Martin Cooper. The first ever invented phone was very big as well so it was pretty hard to use.
knowing that sound gives off waves, like ripples in water, they travel into the mouth piece there the sound waves are copied by the trasmitter behind the transmitter are carbon grains that when an electric current is traveling makes the grians vibrate and that alters the resistance of the grains as a whole. In this way the sound makes more and less current flow in the circuit in proportion to the sound.
At the other end was a coil of wire within a magnet attached to a diaphragm. The variations in current caused the wie tomove in the magnetic field and so make the diaphragm vibrate in sympathy. Vibrations (as we learnt at the beginning) move air and this makes sound!

Alexander Graham Bell was the first to patent the telephone. Attributing the true inventor or inventors to a specific invention can be tricky business. Often credit goes to the inventor of the most practical or best working invention rather than to the original inventor(s).
Telephone was built by Alexander Graham Bell and Thomas Watson.
The concept of the telephone is comprising two diaphragms connected by a taut string or wire. Sound waves are carried as mechanical vibrations along the string or wire from one diaphragm to the other. The classic example is the tin can telephone, a children's toy made by connecting the two ends of a string to the bottoms of two metal cans, paper cups or similar items. The essential idea of this toy was that a diaphragm can collect voice sounds from the air, as in the ear, and a string or wire can transmit such collected voice sounds for reproduction at a distance.
The phone was automatically connected to the main network. All you had to do was talk and the receiver would hear everything.
because it is functioning
nope or the 2nd or the 3rd.

At the same time as the first. If you think about it, one telephone is kind of useless.
the frist telephone looked like a typewriter and needed a lot of power to work
A battery that was wired to a needle that converted sound waves into an electric signal which traveled along a wire to a receiver made the first telephone work. It was invented by Alexander Graham Bell.

No, no one wished to buy the first telephone until it was proven to work when he made two
Alexander Graham Bell is credited with the first electrical telephone in 1876. Modern phones still use the basic principles of his work.
1876
An alternative number is a second [telephone] number, to be used if the first does not work.
Yes it did! But it was improved in 1901!
If you mean telephone, many people where involved in the process but it is usually said that Bell and Watson produced the first commercially made telephone.
