How can we handle outgoing fax calls?

问题

We have a server "Elastix". Is there a way to make something like this?

If someone calls on fax machine, write this behavior in database and hangup immediately. 

I heard about AMD application and read a lot of information, but still don't quite understand, how to make it do what I need.

Can you help me with solution, please?

Thank you in advance!
