Method for acquire verification code of mobile phone

The acquisition method of verification code is as follows:

The system will directly dial the user's phone number and inform the verification code on the mobile phone. Users need to enter the verification code in the system to complete the verification.

3. Voice verification code: For some users who are visually impaired or inconvenient to read short messages, the platform or application will provide voice verification code. The system will generate a voice verification code and automatically dial it to the user by phone. The user needs to listen to the verification code and enter it.
