The question is why does kannel not get an ACK on the connection?
UCP 60 is required when you open the session but you already have a 
session. If it broke, then the TCP stream is closed and kannel detects 
that and would reopen a new session with 60. Maybe there's a firewall 
in the middle playing a bad game so you wont notice the TCP stream 
being closed.
