4.2 Query extension number
The default extension number is 8000-8255, corresponding to physical 1 to 256.
[Query extension number and physical port number]
After extension off-hook, then dial #97 to listen to the system voice broadcast.
[Query the physical location of the machine]
After extension off-hook, then dial #907 to listen to the system voice broadcast.
The system will broadcast four digits. The first two are the board number and the
last two are the serial number inside the board, which can help users quickly locate the
physical port position of the extension and facilitate the line change.
Note: 5D extension board is 16 lines. The board numbers 01 and 02 are in the
first extension board, 03 and 04 are in the second block, and so on.
