I also got this code, but in my scenario the called party didn't generating fax tone. I have tested FreeSWITCH with Images as well but never got such kind of code in that case.

If you have graphics, the pages generally take a lot longer to send. It 
is not uncommon for T.38 gateways to have stupidly short timeouts, which 
will cause a call to drop after a page has been in progress for just one 
minute, or one and a half minutes. Could that be your problem?
