I tried to install mediaproxy but it looks tricky to install (many dependencies, including kernel specific configurations) :-( and I would like to stick to rtpproxy for performance reason.
There is also the often unacknowledged but nevertheless significant fact that AG Projects' political alignment is much closer with the OpenSIPS camp and that support for mediaproxy <-> Kamailio is, as far as I can tell, a secondary concern at best for AG. At the same time, the Kamailio leadership appears to have much more perspective and standardisation on rtpproxy, as well as whatever RTP forwarding module is being lifted from IPTel.org for SIP-Router.
At the same time, it is not entirely clear to me that rtpproxy offers a performance benefit. Although it is small, lightweight and written in C, it is subject to the constraints of userspace scheduling. MediaProxy 2.0 uses API hooks into the kernel's IP forwarding subsystem, which could potentially yield a performance benefit. I don't know that any attempts have been made to undertake a comparative study to determine this.
