> Asterisk needs urgently to push the RTP engine to the Kernel, away from
> userland, like professional and commercial softwares do. I measured the
> cost of passing call from a public IP to a private 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.
