Technologically there is no problem that prevents telephoning to a public phone booth. However, the line that provides service to telephone booths in Spain, as well as in most of the neighboring countries, does not allow the reception of calls. But there are exceptions: some hard-to-reach Spanish towns have only one line, which is usually public and enabled to receive calls. In the United States, public cabins have this service.
On the other hand, when someone calls from a cabin to a telephone with a glass screen, a number appears that corresponds to the identification code of the cabin. If he is called, no one answers.
