What if I can't send the SMS verification code?

At present, the mainstream verification method is SMS verification code, but there are also some problems in this verification, such as: the problems you encounter, the delay in sending SMS, or the inability to send it at all, and the verification SMS is directly mistaken for spam because of some security software on some users' mobile phones. To this end, developers must look everywhere for high-quality and reasonably priced SMS channels. In the process of searching channel resources, they often spend a lot of time and energy and the cost of trial and error.

Therefore, it is recommended to use voice verification code. The user enters the mobile phone number and clicks to get the voice verification code. The user receives the telephone broadcast of the system, and the voice broadcast verification code is input by the user, which is faster than the traditional SMS verification code and has a high success rate. Therefore, voice verification code is recommended. At present, the only vendor I know doing this service is cloopen, which is an open platform with various interfaces and can be quickly integrated into all your websites and apps.
