Lot's of experience and suggestions here. Thanks. I believe it should be theoretically possible to have blip-free RTP streaming through the appliance. Most windows ethernet drivers allow for QoS packet scheduling. If the VMware network bridge driver honors this and syncs the buffers at 20ms frames (or whatever frame size applies) you should be able to schale up a bit and maintain low jitter.
Anyone knows how the VMware network bridge exactly works? -----Oorspronkelijk bericht----- Van: freeswitch-users-boun...@lists.freeswitch.org [mailto:freeswitch-users-boun...@lists.freeswitch.org] Namens Gregory Boehnlein Verzonden: donderdag 15 januari 2009 21:37 Aan: freeswitch-users@lists.freeswitch.org Onderwerp: Re: [Freeswitch-users] [Freeswitch-dev] VMWare voice quality > To the contrary, we have had quite good results in virtualized > environments and you don't really need timing that is that accurate to > make it work. If you don't handle RTP, I'm sure it is amazing. However, if you have to do voicemail, stream audio from the server or do any kind of actual time/latency/jitter sensitive processing, I don't care how much you tune your hypervisor, it's never going to scale. > We work quite well on amazon EC2 for example.

I've not seen this behavior on Vmware ESX 3.5u2. Maybe an issue on Vmware Server or Workstation? _______________________________________________ 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 _______________________________________________ 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
