That's right, for incoming _requests_ with RURI: ngcpct@ kamailio should
unmask the contact URI from RURI. There is no such manipulation required
for the 200 OK response from the UA however.

The problem you are having really looks like the sems bug that Jon is
talking about. The fix however is only in our development trunk and not
in the mr3.4.1 release. I am going to backport it right now and will
reply again when we are good to test.
