[asterisk-users] Detecting a fax

[Floimair Florian]

I would guess from your explanation that the "outgoing" call somehow ends up in your Asterisk machine again, either at the voicetest or fax extension.
You don't answer it in either of the extensions. 
That's what TOOTAI meant.

If this is done in another extension, than this part of the Dialplan is missing in your post. So we can only guess what's going on.
Either post the full dialplan or add some log or cli output (with verbose set to at least 1) so we can have a chance of seeing what's going on.
 
 
With best regards

    It's an outgoing call. I wouldn't expect to answer an outgoing call?
