Voice quality Freeswitch on Centos on VMware EXSi
Dear All, I have installed Freesiwtch on CentOS 5.4 on VMware EXSi. Everything works fine but I keep having voice quality issues 1. Conference call will have gradually built up delay . Up to 10s of seconds for a conference call running for like 10 mins 2. Google talk have very choppy voice quality even I am using G711. I have extrated the RTPs in wireshark (less that 1 % packet lost) and play it using media player, the media is also choppy. For guest OS clock issue. I have already set clocksource=pit in linux boot option and NTP in linux but seems the problem still persist. Is there any suggestion that I can get the problem solved ? Or I have to run FS in real machine instead of visualization? Thanks a lot for your help
Just avoid virtualization - I think that's the only solution.. /Peter Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Storm Demo Skickat: den 20 april 2010 13:26 Till: freeswitch-users@lists.freeswitch.org Ämne: [Freeswitch-users] Voice quality Freeswitch on Centos on VMware EXSi Dear All, I have installed Freesiwtch on CentOS 5.4 on VMware EXSi.

And an easy one, by the way. Just quantify the amount of time you'll use to "maybe" get it right... When virtualization will be really ready for voip, we all we'll be aware of that ;). Don't fear you missed that while you were in Spring holydays -giovanni

there is some other common vmware issue related to networking that causes you to get 2 of every RTP packets. if you want to use virtual I suggest openvz as it works very well with FS. On Wed, Apr 21, 2010 at 9:18 AM, Peter Olsson < peter.olsson@visionutveckling.se> wrote:
