On SmartSMSSolutions, we give you the option to send Voice OTP directly on the website, with all you need being the phone number you wish to send the Voice OTP to and the Voice OTP code.
Additionally, you will need to select an OTP Class as the first option on the page. OTP Classes being templates of pre-recorded Voice OTP formats. Note that the class you select will determine the number of digits you will use in your OTP code section, to ensure delivery. If you are not satisfied with any of the provided OTP classes, you can then request a custom Voice OTP class.

Alternatively, your OTP needs might be to have this service on your own application, be it mobile or web, and when users on your platform need it to complete a transaction, it is automatically sent to them.

On the page, click on Voice OTP as one of the options found on the listed menu to the left. You can then follow the integration process from the documentation found there.
