How to send a short message back to the caller group?

There are two ways, one is to hang up the SMS, which requires connecting the computer, landline and hanging-up equipment, and then setting the content in advance, which can be sent automatically after the call. The problem is that there are fewer companies now, the SMS is becoming more and more standardized, the audit is becoming more and more strict, and the SMS sent by hanging up is difficult to manage, so many companies have cut it down.

There is also a need for you to sort out the call number, and then use it to find a reliable platform, such as 238, Haoyu information connection, import and then send, which is a bit troublesome for your reference.
