[niu-chinauicom]

This API allows the caller (application server/Internet device/software/mobile phone client, such as mobile phone App, Web, PC client, soft terminal, etc.) to send verification code to the called mobile phone users quickly and accurately by voice call based on IMS network in the way of calling with the application, so as to avoid the disadvantage of prolonged receipt of SMS verification code and easy interception, and improve users' perception.
