Hello, RR!

Yes, that is all that you need to fix the freeTDS
"pseudo-thread-safe" problem.

And you should know nothing else to enjoyable using of Asterisk!

Congratulations!!!  :)

I spent much more time to find the problem, find and apply the 
appropriate patch, fix some bugs, then apply that patch manually to new 
version ...

About tables and views - it's some possible causes:
1. Sybase/MS SQL protocol isn't open, so FreeTDS isn't implement all of 
the features of such database servers.
2. I'm not guru in different databases and in specifications, but it's 
can be ODBC limitation (feature). Because ODBC was specified as 
universal database access engine. So, some database servers possibly 
haven't substance like "view".
