How to call a certain external mobile number and, if the subscriber picks up the handset, immediately terminate the connection?

Question

Asterisk

There is FreePBX. Tell me how to call a specific external mobile number and, if the subscriber picks up the phone, immediately interrupt the connection so that money is not withdrawn. This is necessary to verify the applicant's phone number in his presence. Does anyone have other ideas on how to do this.
