Today, it is necessary to add to the telephone number, the local area code, and a company prefix, if the user wants that the phone call is made by anoth er company. If the user lives near another telephone area in his daily phone calls, he has calls to the neighbour area. That obliges the user to dial the local area code. With this invention the user only dials one digit more, instead of three digits. Today it is possible to use several communications wires. There is a continuous changing of the phone call price and the user h as difficulties to keep informed. The simplification system for telephones studies every telephone number based in a logical scheme and with the data that is in the memory, and also counting the digits, and counting the time. Then deletes the extra digit if it exists, and adds, if necessary, the local area code, the company prefix and chooses the wire of communication. It can also receive a normalised message by the wire of communication, that message is studied and then automatically or after confirmation by the user, changes the telephone company, that makes the phone call.
