I am trying to use openser purely as a RTP proxy using mediaproxy. All
SIP request are forwarded through to a central server. However, the RTP
proxying does not work. The mediaproxy session gets set up and both end
points get given the same port on the mediaproxy - is this correct? Both
end points forward RTP packets to the mediaproxy but they are not forwarded.
These are my log entries for the call and my config is attached:

I have ethereal captures showing the SIP and RTP packets if they are useful.
Can anyone help me?
