However, considering that in practical applications, the number of the voice device may be different from the number of the fax machine (especially for the scheme of forming a service subject that provides wireless fax services through a VoLTE phone and a fax machine that you carry with you, because VoLTE The phone can be changed, so the number of the VoLTE phone can also be changed, from the situation that the number of the voice device and the number of the fax machine may often be different), and the numbers saved between many units or individuals are more stable. number of the fax machine. In this case, in this embodiment of the present application, the dialed number may also be the number of the recipient's facsimile machine. In order to ensure that it can be connected to the receiver's voice device according to the number of the receiver's fax machine, when the receiver's voice device is connected to the receiver's fax machine, the number of the receiver's fax machine and the communication address of the receiver's voice device (for example, receiving The number of the voice device of the receiver) is associated and reported to the base station, so that after the voice device of the sender sends the dial number to the base station, the base station can find the communication address of the voice device of the receiver according to the dial number, and then realize the voice of the voice device of the receiver.

It should be understood that if the fax machine of the sender does not receive the fax negotiation response within the set period, or the content of the fax negotiation response indicates that the negotiation fails, the current wireless fax process can be ended.

S104: The recipient's voice device forwards the fax audio stream to the recipient's fax machine.

After receiving the fax audio stream, the receiving fax machine can decode the fax audio stream in the corresponding data decoding mode according to the data encoding mode described above, restore it to original data, and then print it out.

Exemplarily, at the end of the fax (ie, after all fax audio streams are sent), the sender's fax machine may send a fax end tone of a specific frequency to the sender's voice device according to a standard fax protocol.

The sender's voice device sends the fax end tone to the receiver's voice device through the established voice wireless connection, and the receiver's voice device forwards the fax end tone to the recipient's fax machine.

After the receiving fax machine receives the fax ending tone, it stops receiving the fax audio stream, and decodes and restores the received fax audio stream to original data and prints it out. At this point, the fax process ends.

After the fax process ends, both the sender's voice device and the receiver's voice device can send out a prompt tone to remind the user that the fax has ended, so that the user hangs up.
