Single use of a PIN of a PIN Set


I’d like to ask you guys whether is possible to limit the use of a PIN of a PIN set to only one time.
I’d like to use this to track a call time and duration. For example, I’d like to know when a PIN was used and what was the duration of that call.

Is that possible?

What other alternatives may I have to do this?

Thank you, very much.

Sounds like you are trying to do calling cards… Your best solution here would be a custom module that you could use to issue pins and destroy them.

Good idea!

Is out there some documentation to build custom modules?
Or we must go out for paid commercial modules?

Thank you,
