I'll also warn that if you do intend on doing anything with
rtpengine/webrtc2sip etc. you'll need Openssl 1.0.1j or better so that it
has the proper support for DTLS-SRTP. This means you are sort of SOL if you
are running CentOS5 unless you plan on building Openssl 1.0.1 manually. The
websocket module is also not in the Kamailio repositories for CentOS5 and
you would need to build it yourself. I'm being rather specific with
Cent/RHEL just because I ran into this problem and wanted to throw it out
as a warning...

Also rtpengine won't work in kernel mode in Cent/RHEL 5. Everything is
smooth sailing on CentOS 6.

:)
