Change registration type from sms to call back

CSM Bitrix
It is required to change the following in the existing registration/authorization form:
1. When registering at the moment, send an SMS with a password. Implemented through the sms.ru service. You need to do the same, only through a callback.
2. If a person has forgotten the password, it is now also implemented via SMS. You need to do a password recovery to the mail.
