>     Asterisk needs urgently to push the RTP engine to the Kernel, away

>     IP, like typically a Session Border Controller may do. In
>     Asterisk, ulaw, no transcoding, it takes 1.7% of a 3 Ghz core. If
>     the packets where flowing through the kernel, like iptables does,
>     it would take 10% if the CPU. Asterisk then could be used in
>     hundreds of different roles in the enterprise.  PJSIP has no
>     importance at all, this is the big issue. I suggest the developers
>     look at an open-source package and adapt the code, is called
>     rtpengine. It uses a kernel module to do the job.
