I think this was fixed a long time ago. We should lock on the tag in  
the first
200 OK in pedantic mode. I've run these tests and SIPit and Asterisk  
handled
it great. Getting multiple 200 OK is another story.

We do try to fix stuff if proper  bug reports are filed with  
bugs.digium.com.

If this bug has re-appeared lately, then it needs to be re-fixed.
