[Serusers] mediaproxy problem

[Martin Bangiev]

Hi guys,
I'm trying to make X-lite to register to the ser server and the ser 
server to pass the invites to an asterisk box. The asterisk has only to 
play some sound sample in responce. And I want the RTP to pass through a 
mediaproxy. My X-lite is behind masquerading.
I installed all the software needed for the tests and used the ser.cfg 
located in the mediaproxy.so module directory. But here is what appears 
in the ser's console:
     0(25804) error: mediaproxy/sendMediaproxyCommand(): can't connect 
to MediaProxy
     0(25804) error: mediaproxy/sendMediaproxyCommand(): can't connect 
to MediaProxy
     0(25804) ERROR: on_reply processing failed

And the conversation starts without using the mediaproxy.
And when I hang up comes this:
     0(25804) error: mediaproxy/sendMediaproxyCommand(): can't connect 
to MediaProxy

Where the problem could be (the mediaproxy is running)?
And are there any examples about the domain.so module? I'm not sure if I 
configured it correctly becouse of insufficient documentation I found.

I made this run with the rtpproxy, but I want to make it with mediaproxy 
too.
Thanks in advance.
