Hello,

plz have a look at issue 17641 
(https://issues.asterisk.org/view.php?id=17641) and try the patch from 
there, or atleast dont use answer before ReceiveFax cause its buggy 
without this patch.
what i also see in your log is that dahdi doesnt recognize the CED Tone 
from your fax so the echo canceler isnt turned off, which could also be 
a problem. (Row 21 to 26 in your log)

best regards

steve
