Is it possible to configure the OpenSER with nathelper/mediaproxy to act as a remote-side
outbound proxy? I have tried to make it, but unfortunately still can not do that. It will
be best if someone shares a working openser.cfg file. The best I got is that when the UA
makes call it works OK, but the UA can not be dialed from other UA in the network. Maybe
it is not even registered.
