Setting up sending SMS messages to Ru in Bitrix 24

Hello.
It is necessary to configure sending SMS messages to your number (not the client) through the robot.
SMS ru is configured, letters of guarantee are accepted, letter representatives are added, bills are paid.
SMS are sent.
BUT.
They created a robot, set it up so that when filling in the field, it should work and send an SMS to the desired number. It doesnt work...
