The biggest difference between the two call flows is that the 3.10 trace
uses UDP whereas the 3.11.8 trace uses TCP.  The NAT traversal feature
introduces new headers and URL parameters which increases the size of
the message.  One possibility is that the recent merge of the NAT
traversal code pushed the size of the message beyond 1300 which caused
TCP to get used and perhaps there is a TCP incompatibility between Snom
and sipXecs.  The other possibility is that the new headers and URL
params confuse the Snom phone. 

I may have a Snom phone here.  I'll try to configure it for TCP only and
point it at a 3.10 system to see what happens.  I'll post back to let
you know the results.
