Hi Klaus,
That worked perfectly, thanks!
One thing I've noticed - nathelper is sending OPTIONS pings to all
contacts, regardless of the incoming socket. So both servers are sending
pings to all clients. I am assuming this is because in our tests the
clients and servers are on the same subnet - do you think this is the case?
Obviously, in a production environment where clients are behind NAT, it
only makes sense to send keep-alives from the server a client is registered
on.
Thanks again,
Charles

If the add the Path header manually, then it is not
seen by the
registrar/usrloc module, asthe header will only be added when generating
the "to be forwarded" message - and this never happens as the message
terminates on the registrar. You could try msg_apply_changes() after adding
the Path header.
