Hello, landlord: Guowei WSQ4 16, which means that the configuration of this switch can be connected to four external lines 16. Cannot start with 9, because the system only accepts 1 .2 .8? The extension number at the beginning is 2 to 4 digits. If you want to fill a 2-digit extension number, you can only fill 89, and the remaining 7-digit extensions can only be 3-digit extension numbers, but the system does not accept duplicate numbers. For example, if the extension number is 8 1-89, the remaining seven extensions can't be 8 1 1, but only 80 1.

The specific operation method comprises the following steps:

Pick up the phone at will and press #787 1967590, enter 29 * * * and hang up (clear all extension numbers).

Repeat the above operation: press #787 1967590 to enter 29 after hearing the prompt tone after lifting the machine, and enter the port number 001* 81* 002 * 82 ... 009 * 89 * 010 * 80/kloc. ...
