Sending codes by voice message

This service allows you to send digital codes to confirm certain operations using a short voice message, which is much cheaper than sending codes in SMS messages..

To transmit the code, it is necessary to send a special voice message (voice) to the subscriber with the word code, according to which the subscriber will receive a call from a random number from a given pool. When receiving a call, the subscriber needs to pick up the phone, the system will automatically sound the code. The four digits voiced by the system will be the secret code that the subscriber will need to confirm the operation in your service.

Sending codes by voice message can be used as a cheap alternative to SMS messages to solve the following tasks:

• confirmation of registration of a new user by phone number;
• sending codes when placing orders on the site;
• getting access to various services linked to a phone number.
