Dear Tim, Kofi and Friends,
 
As regarding to MediaProxy and OpenSER, below is my config file, i'm using Fedora Core 3, OpenSER 0.9.5, MediaProxy 1.3.1 and it's working :)
Please find my working openser.cfg and mediaproxy.ini below.
 
Installation dirs as ;
 
OpenSER Config : /usr/local/etc/openser/
OpenSER Modules : /usr/local/lib/openser/modules/
MediaProxy : /usr/local/mediaproxy/
 
** Files "rtp-asymmetric-clients" and "sip-asymmetric-clients" are copied to /usr/local/etc/openser/ which is same with openser.cfg and note that both MediaProxy & OpenSER starts @ boot.
 
Thanks,
Ozan
