[snip long trace]

 From here http://www.cnes.com/causecodes.html:

*Cause No. 27 - destination out of order [Q.850] *
This cause indicates that the destination indicated by the user cannot 
be reached because the interface to the destination is not functioning 
correctly. The term "not functioning correctly" indicates that a signal 
message was unable to be delivered to the remote party; e.g., a physical 
layer or data link layer failure at the remote party or user equipment 
off-line.

I am betting this is simply what my telco is sending because they were 
unable to pass the call on to Sprint.  It would be more informative 
perhaps to see what kind of trace the telco has of the handoff to 
Sprint.  I'm going to see if they will give it to me.

Cheers,
