I suggest you go to China Telecom to get a copy of your fixed-line phone bill to see if there is any abnormality?

This is my analysis. It is very similar to the 168 series information station, with one switchboard and N operators below.

But it saves the steps such as automatic transfer. Manual transfer makes it feel as if it is an ordinary switchboard, and your Q friend's phone number is an ordinary extension below.

Based on experience, this number 96697706 should be the SP code, because many telecom SPs (information providers) have 4-8 digit codes starting with 9 or 2, such as CCTV An SP service code of -5 is 9999266, and there are also Shanghong Tujiateng 9555. For these information stations, you can either call in, receive the extension, and the operators will chat with you, and you will be charged according to the length of the call, or you can use group messaging. device, send SP information to PHS, etc.

You can imagine this: There are many operators in this company, and they are given a basic salary, and they have to rely on themselves to increase the call volume. These operators use QQ messages or other methods on the Internet to let others make calls to improve their performance.

A bit clever
