The telephone exchange needs to control multiple telephones, so it needs to assign telephone numbers to different telephones. Generally, the telephone number will be automatically assigned according to the inserted line during installation, and different telephone numbers can be assigned according to the department during debugging. If you want to change the extension number of the telephone, you need to know the port number you changed first, and then delete the original extension number on the telephone exchange to make the change.
