Sorry for the delay in answering this - I am not in the office this
week.  Using Greger's advice, I was able to get the detection of same
NAT working (sometimes - depends on me calling nathelper I think), but
due to other pressures (to do with getting cascading rtpproxy set up
with rtpproxy running in bridge mode) I have had to delay implementing
the solution fully. When I do I will of course share with all...  I
think that it will be a case of doing the detection before messing with
the contact with nathelper, and then using that to decide whether
fix_nated_contact is called.
