Fax and stream_file

Hi,
I want to add new functionality to my fax platform. Now fax calls another party and gives the fax signal to initiate the fax transfer. I would like to add wav streaming before the fax initiates the call. Anybody some ideas, I was thinking about that, but it is almost imposible to be done in theory. I want to add “Please, give the fax signal”, and after that fax singnal. It happens that some of the fax machines have to be switched manually by a secretary.

my idea is to use Agent for that , thanks :smile:
