How old is the Cisco software? It appears they completely changed their 
T.38 software platform a couple of years ago. Before that is was awful. 
I wasted a lot of time, while developing my T.38 platform, hunting down 
problems that turned out to be broken Ciscos. Since the new software has 
spread into the field, the complaints have largely gone away.
