[Users] Mediaproxy issue

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: Apr 6 21:33:11 lepus mediaproxy[27804]: command request 89C6D172-1DD2-11B2-BBB5-97F0622A5395(a)192.168.2.3 192.168.2.3:49200:audio 202.74.181.144 sipone.com local 202.74.164.72 remote SJphone/1.60.299a/L=20(SJ=20Labs) info=from:61028679%20@sipone.com,to:1300130710@sipone.com,fromtag:1870227267254482412,totag: Apr 6 21:33:11 lepus mediaproxy[27804]: session 89C6D172-1DD2-11B2-BBB5-97F0622A5395(a)192.168.2.3: started. listening on 202.74.164.44:35038 Apr 6 21:33:11 lepus mediaproxy[27804]: command execution time: 1.54 ms Apr 6 21:33:11 lepus mediaproxy[27804]: command lookup 89C6D172-1DD2-11B2-BBB5-97F0622A5395(a)192.168.2.3 202.74.164.72:20750:audio 202.74.164.72 sipone.com local sipone.com unknown Cisco-SIPGateway/IOS-12.x info=from:61028679%20@sipone.com,to:1300130710@sipone.com,fromtag:1870227267254482412,totag:BDA88B14-B58 Apr 6 21:33:11 lepus mediaproxy[27804]: command execution time: 0.36 ms Apr 6 21:33:19 lepus mediaproxy[27804]: command delete 89C6D172-1DD2-11B2-BBB5-97F0622A5395(a)192.168.2.3 info= Apr 6 21:33:19 lepus mediaproxy[27804]: session 89C6D172-1DD2-11B2-BBB5-97F0622A5395(a)192.168.2.3: 0/0/0 packets, 0/0/0 bytes (caller/called/relayed) Apr 6 21:33:19 lepus mediaproxy[27804]: session 89C6D172-1DD2-11B2-BBB5-97F0622A5395(a)192.168.2.3: ended.
