So far so good.  The receiver accepted our DCS signal and the 
corresponding TCF training signal.  Now we move on to sending page image 
data...

The logging isn't set high enough to see, but I would assume that 
between 13:45:56.43 and 13:46:27.51 HylaFAX was sending data to the 
modem, ultimately terminated by DLE+ETX, and then HylaFAX began to wait 
for an OK response... but instead it got a NO CARRIER response.

In the iaxmodem world this means very clearly that the call was 
disconnected somehow (within Asterisk or the receiver hung up or 
something of that nature).

This ERROR result is because the modem is already on-hook.  iaxmodem 
goes on-hook when the call is disconnected.

So you'll need to investigate why the call is disconnecting.  Probably 
the receiver is hanging up, and you'll want to figure out why.

Thanks,

Lee.
