Principle of free calls and principle of free calls

Micro-conferences do not directly implement voice call services through Internet traffic. They are called back-to-back network phones.

  • Principle:
    Micro-user calls → micro-Server Response → micro-server calls back to the caller, and the server calls the caller → caller (micro-user) establish a call with the recipient.
    That is:

Micro-calls belong to the callback class. There is a callback process. If you log on to another device, you can only call the phone number bound to your account, in this way, you cannot establish a call with the recipient. To use the WeChat account properly, you are advised to ensure that the mobile phone number used is consistent with the WeChat account.

Because micro-systems implement server-based callback, some limitations exist. The micro-conference server does not provide network telephone services for all calls. For example, if you call a fixed-line or 10010 service number, the micro-conference will directly call the system telephone function.
