Folks;Bear in mind that the frequency is (X)Hz * (num cores), hence saying 100Hz on a dual core winds up being 200Hz.
My setup is 250Hz on a Dual-Core and the quality is perfect.Oh, btw folks, don't attempt to do anything involving QOS (be it TBF, CBQ, HTB, or whatnot) on anything less than kernel 2.6.28.4
I don't know why exactly that is, but extensive testing here in the lab showed that this was entirely FUBAR until 2.6.25.7 where it got better, but not perfect until 2.6.28.4
(I may not be exact on the revisions, but close enough...)There's also some options in the kernel that you must disable (not compile in) if you expect packet shaping to work.
If there's interest in this, e-mail me directly and I'll see if I can toss it into the FS Wiki some time this upcoming weekend.

Google that options and you will find lots of discussions that will clarify your mind. Here you will find a simple explanation: http://www.smk.co.za/2007/07/21/a-tickless-kernel/Thank you for the references. I think I'll modify my kernel parameters in the grub configuration, since I am using Debian kernels at the moment. (I do know how to compile my own, which I will gladly do if it becomes necessary)._______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
