[asterisk-dev] IAX2 changes - thank you!

[Mihai Balea]

In our production systems we don't use registration, all clients call  
in, no calls go out.  As a consequence, our stress tests are designed  
to simulate that.
So it looks like there are some code paths that we have not covered  
and might still have some issues ...
