What does a small horn sound mean?

When you make a phone call through the micro-speaker, the other party will display the prompt "The other party's mobile phone is not at hand, please redial later".

Because the micro number and the size number are two WeChat accounts on the same device, when using the micro number to make a call, the other party will see that the incoming call shows the number of WeChat trumpet. At this time, the WeChat trumpet is online, but the other party does not answer, or the other party's mobile phone is mute or unable to answer, then the caller will hear the prompt "The other party's mobile phone is not at hand, please redial later". This is because the WeChat phone is transmitted through the network, not through the cell phone signal. Even if the other party's mobile phone is not around, as long as the WeChat trumpet is online, you can communicate by WeChat phone.
