Does such formula exist ? And do you have other functions/apps that demands cpu power that needs to be taken into the formula. And please skip that disclaimer you have in the bottom ! /Mats On 5/15/07, Khaled Chehab <kchehab@xplorium.com> wrote:> > > > Do any one knows the formula to calculate memory and cpu usuage for > channel on g729 codec,to know the hardware required for 100 concurrent > call. > > > > Regards >-------------- next part -------------- An HTML attachment was scrubbed...

G.729 is a compromise of bandwidth vs. CPU power. It takes more CPU but less bandwidth. It depends on what your want to do with the G.729. Pass through does not involve any transcoding, that I know of, so it is just an RTP packet movement, no different than the cost of other pass through codecs. I did work on converting G.729 to G.711 to disk storage in real time and that took about 3% of a Xeon CPU for full duplex. Memory wise each convert call might have used 640KB in buffers and trash, but not much.
