 From a quick look at the code, I don't see anything obvious, but based on your 
output, it does appear to be broken.  In general, it's always best to test the 
latest version, but after that, post it on http://bugs.digium.com and someone 
will take a look.

Be sure to include the SIP trace of the call that demonstrates the problem, as 
well as the console output.
