Will fixed telephones eventually disappear?

It can only be said that the use of fixed telephone will become narrower and narrower, but it will never disappear, because many enterprises have fixed contact information, that is, fixed telephone. They have a department dedicated to foreign exchange. If it is a mobile phone, it is obviously not so formal and convenient. Then this fixed telephone can also let this department take turns to be on duty, which has no influence and is more important in some important occasions. It is an inevitable need of existence. There is an internal telephone, and only people on this line can communicate with each other. This is an internal phone, which is far more convenient than a mobile phone. Because the internal phone only needs to remember the last few digits and the mobile phone needs to remember 1 1 digit.
