So, firstly when one person speak, your voice is converted into electrical signals. These electrical signals travel through the telephone's network, which could be a traditional landline network or a mobile network. At the receiving end, the electrical signals are converted back into sound waves, which are played through the speaker. Thus, both people can hear and chat with each other even though they are not in the same place
