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.
