Hi,

I have a 1.6.2.6 fax installation with a FFA license which seems to be
installed correctly (in fax show stats, I see that I have 1 Digium
G.711 licensed channel, and 1 Digium T.38 licensed channel).

When trying to call my business line with a fax machine, it looks like
it’s ringing to my asterisk box, then transfer the call to my extension.
In the logs, I see (after the line where it says that my extension is
ringing): chan_sip.c: Fax detected but no fax extension.

How come does Asterisk even try to ring my phone? It seems that the
detection (which should append BEFORE any phone ring) does not work, and
I have no clue where to look at.

In case this helps, I’m configuring the installation with FreePBX 2.8.1.4

Thanks,

    Do you imply you want to share a single phone number for both fax and voice
    calls or are dedicating a number to fax handling ?

    How Asterisk should detected an incoming call is coming from a fax machine ?

  • Sorry for the top post.

    A valid fax extension is an extension named ‘fax’ in the incoming context for that peer. I.e:

    exten => fax,1,Verbose(1,Incoming fax call detected)
    exten => fax,n,ReceiveFax()

    You would obviously have a much longer definition, this was just a quick example from my phone.

    Thanks,
