Hello,

The NoOp output was not displayed at all. I'm assuming because of the
failure in the ReceiveFax application. In fact, the verbose output
was:

  == Using SIP RTP CoS mark 5
  == Using UDPTL CoS mark 5
    -- Executing [99999 at demo:1] Set("SIP/192.168.0.253-b7a96b70",

[Mar 24 18:47:09] WARNING[15248]: app_fax.c:650 transmit: Transmission error
  == Spawn extension (demo, 99999, 4) exited non-zero on
'SIP/192.168.0.253-b7a96b70'


And no, the file /root/santi/fax/incoming.tif was not empty. It
contained the "correct" received fax.

Oh, I forgot to add I'm using spandsp-0.0.6pre7.

I copy here some more lines of the debug info that maybe can help to
understand what's going on:
