A craft ornament type multifunctional number filter comprises an interface circuit, a microcontroller, a line switch, a memory and a man-machine interface circuit. The input end of the interface circuit is connected with an outside line end of a telephone, and the output end of the interface circuit is connected with the microcontroller. The microcontroller is connected with the line switch, the memory and the man-machine interface circuit. The line switch is in series connection between the outside line end of the telephone and user equipment. The man-machine interface circuit is formed by a keyboard, a display and an acousto-optic prompting device. The effects of the craft ornament type multifunctional number filter are: automatic reception of office hoax faxes are prevented, and black-list or non-white-list prank calls are rejected automatically, so a lot of screening work is avoided, the workload is reduced, and resources are saved; the filter enables a desktop in an office or in a family to be ornamental and practical; and a function of storing small things in work and life is achieved, and the filter is prevented from only having a single function.
