We can only guess about the topology. My guess is that here is a router with a
public address and that the node that is hosting openser does not have an
interface on the public network. The router could be using port forwarding or
it could be a NAT binding. Then it would _appear_ as if the message went
directly from the public network to 192.168.2.10:5060 depending on your point
of observation.
For INVITE we rely on the registrar for the public address. For ACK we rely on
the RR list.

It shouldn't be a problem since the gateway seems to have an interface to
that private network. In fact, note that the first INVITE from gateway goes
to the private address of OpenSer:
