How to get voice verification code

This question is actually the same principle as SMS verification code. When the user sends a verification request on the page or APP, the system will trigger the preset mechanism technology and send a voice verification code to the user's mobile phone, so that the user's mobile phone can successfully receive it. It should be noted here that sometimes the user's mobile phone will be temporarily unavailable because of the poor signal of the mobile phone itself or the unstable voice sms channel. You can wait a while or try to send the application in a few minutes. If it still doesn't work, you need to find a platform to find problems.
