PSTN (Public Switched Telephone Network) and method, device and system of radio mobile network dialing

Abstract

The invention relates to a PSTN (Public Switched Telephone Network) and a method, a device and a system of radio mobile network dialing. The method comprises the following steps of: receiving a telephone number packet sent by a server and selecting a signal path for the telephone number packet; when a fixed-line telephone signal path is selected, carrying out data processing on the telephone number packet; and sending processed data signals to the PSTN. In the invention, telephone numbers are directly called out on the server installed with CRM (Customer Relationship Management) software, which can achieve the purpose of calling a radio mobile network by a radio mobile telephone set; and a fixed-line telephone set is used for assisting to call the PSTN so that the problem that a PC (Personal Computer) installed with the CRM software of a user cannot be used for directly calling a client telephone number in the prior art is solved, the workload of the user is greatly reduced and strong practicality is obtained. Meanwhile, the PC installed with the CRM software can be used for receiving incoming calls from the radio mobile network and the PSTN and displaying corresponding telephone numbers so as to be convenient to use for the user.
