I called her, but she didn't answer the phone. The one who sent the text message and reported it also succeeded. Could she have knocked me out?

If it is possible for an old version of the phone, even if my original 6300 is blacklisted, I can't refuse to answer it directly, but the call doesn't ring;

Another possibility is to mute the phone directly without hanging up (many mobile phones have this function), or it is possible.

There are many situations. I suggest you ask her directly to avoid guessing.
