The landline number, I called and said it was empty, but I received a reply later. What happened?

Hello, the landline prompt number is empty or the user is not logged in or the number you dialed is wrong. You can receive hang-up information after hanging up. Indicates that the number is in a multiplexed state, but the call is transferred to a fixed line. Go to the specified number. If the other party doesn't want to answer your phone or for other reasons, he will transfer to an empty number. When you call a landline, you will also receive an on-hook message. Hang-up SMS is opened by the other party and paid by the other party.

It's very simple to transfer an empty number, such as 0755-0000000 or 0755-999999 in Shenzhen. These numbers are empty, so you can transfer the fixed line to similar numbers.
