Interesting... I just ran into the same problem with no firewalls or 
nating involved. This one is an spa3k but with exactly the same issue. 
Had been working just fine, but now fails with SVN-branch-1.2-r34400. 
All other sip phones are functioning fine.

An ethereal trace only indicates the spa3k is returning "busy here". I 
don't see anything wrong with the initial sip packets, but didn't have 
the time to dig to deeply into it either.

I also made sure DND, Call Forwarding, etc, was not the issue.

Looks like we need to open a bug on this. I'll be out of town for the 
next week and won't have any access to the boxes for testing.
