As I mentioned in another email, you need to have the development version 
of libnetfilter-conntrack (usually named libnetfilter-conntrack-dev) 
installed. If after installing that you still have issues compiling, post 
the compiler messages here.

Actually that is no longer accurate. This was true with mediaproxy 1. With 
mediaproxy 2, it uses all the CPUs you have since the forwarding is done 
in kernel space so it doesn't need to run more than one copy on the same 
host for this. It scales much better then rtpproxy as it doesn't need to 
spend time to copy packets from kernel space to user space and back. 
Instead they are just forwarded by the conntrack layer directly at kernel 
level. And mediaproxy 2 has all the accounting features of mediaproxy 1 
plus some more.
