Can WeChat voice call receive information at the same time?

Voice call while watching video. If you watch short video, it's the same mobile phone, but the other party can't hear the sound. The voice calling function of WeChat was strongly hindered when it was launched. Wechat voice call is a big behavior that can directly replace the call function. Wechat knows whether the other party only needs to send a WeChat call to the other party during the voice call. If the line is busy, it's a call.

Brief introduction of WeChat voice call:

"WeChat Phone" provides a dial, which can directly initiate a call through WeChat. The called party of the service does not need to be a WeChat user, and the called party does not need to connect to the network. Unlike the built-in voice calls of mobile phones QQ and WeChat, which require both parties to connect to the network at the same time, only the caller needs to connect to the network.

Development area: In the WeChat phone page, this service is still in the testing stage, and it is only open to users in the United States, Hong Kong and India, but users in these areas can make calls to mobile phones and fixed telephones in more than 200 countries and regions around the world at very low rates.
