Each switchboard telephone system has a handoff Change the machine and at least one phone, each phone connects to the XML server through the Internet to periodically upload its own phone status. The user of each phone can set the BLF button on the phone to correspond to a specific remote phone. Each phone periodically retrieves the state of the phone of the corresponding remote phone from the XML server and displays it on the BLF of the phone. On the key.

The effect achieved by the present invention over the prior art is that the busy line monitoring function of the telephone telephone can be developed to the far end without being limited to the switchboard telephone system to which the own telephone belongs. In this way, for example, for foreign branches, specific VIP customers, or frequently dialed business calls, users can monitor the busy status of their phones to solve the problem of frequent dial-up to remote phones. The line does not go into trouble. Furthermore, the user can also set the BLF key setting on the phone to the phone number of the specific remote phone, and then dial the phone number when the BLF button is pressed, thereby enhancing the efficiency of daily business operations and saving Valuable work time.
