Hi
I've been anticipating to setup Mediaproxy for more then a week now
without any success.
I've used the following resources as guidelines, but still can't figure
out what I'm doing wrong or missing:

mailing-list: [OpenSIPS-Users] Mediaproxy broken
I use Counterpath softphone clients for my testing.
One on my MacBookPro and other within Windows XP VirtualBox Machine on
same Mac.
I have the Mac Firewall turned off.
I can setup call from Windows Client to Mac Client, but when I answer
call on Mac the call gets dropped immediately, but Windows client still
says calling until it times out and 408 give error.
I can't setup call from Mac client to Windows Client. It tries calling
but after a while the client returns with "Can't Connect" without
ringing on Windows Client.
I've played around with the client Topology configurations on the and
the only setting that gives some light is "use local IP", and this only
on Mac Client.
The only result I get is Mac Client rings when I call from Windows
Client, but then drops call immediately when answer.
What I am looking to achieve is as follows:
1. Media Proxy only be used when Devices are behind NAT.
2. Not use MediaProxy for media when devices are behind the same
Firewall. i.e. 192.168....@brancha calls 192.168.3...@branchb
3. I am very interested in the ICE feature and would really like to get
that working. I guess this will resolve requirement 2?
Here is my configurations to show what I currently have:
