Incoming FAX Detection on Digum Fax License


I have the Digium Free Fax License for one channel, Now my question is how to detect the fax for incoming call. What the things I have to write to detect the fax and receive it.

any idea how to send an email once fax received successfully ?

Thanks in advance, if some one help me out.



  1. Extension fax
  2. Use some logic in “h” extension
