What is the behavior of refusing to answer other people's phone calls?

It is impolite to refuse to answer other people's phone calls. If you don't answer, you can send a text message to inform the caller.

Refusing to answer the phone is refusing to answer the phone. Refusing to answer the phone means that the party concerned may be in an inconvenient state to answer the phone, or may deliberately not answer the phone. Not connected means that the line is busy and I can't get through, that is, I call the other party and the other party is on the phone. Of course, if you can't connect, it may be that the other party's signal is not good, the phone is turned off or refuses to answer.

Specific introduction:

Refusing to answer the phone is a right set on the mobile phone, which means that there are two kinds of intelligent identification of the mobile phone by callers in the network: all restrictions and selection restrictions. When the mobile phone is put on the restricted list, it can't make calls, which is also a self-conservative concept of the owner.

Restrict and refuse to make phone calls and send text messages in the blacklist. After receiving the signal notification, the target mobile phone inquires the blacklist and decides whether to hang up. In fact, the original manual hang-up has become an automation, that is, automatic hang-up. So when people on the blacklist make a phone call, they will display a busy tone, not a phone call or a busy tone, just after one or two rings.

If you start a call, you can turn off the phone in the settings list, such as Haier's call firewall and CLP's call reminder. Only after several rings will a busy tone appear, depending on the response speed of the firewall software installed on the target phone. If the software responds slowly, you need to listen to the callback tone and busy tone for a while.

In order to send out "out-of-service" ring back tone, the mobile company must turn off the mobile phone or directly start the call firewall service, and directly do blacklist query and hang-up work during the mobile transfer process.
