app_confrenrece sucks when its under heavy load.. other then that its ok i guess for low volume.. it tends to crash asterisk once in a while so i dont use it. I used 1000hz kernel with ztdummy but again once the volume goes up the conf calls become choppy. My guess is when the cpu usage goes up on high volume traffic the kernel timer doesn’t get as much preference in resources which causes choppy calls in the meetme rooms. OpenVZ apprently makes use of the hot kernel.. but they dont have a nice gui like xen citrix

Hi Johan,

I’m not using app_conference nor freepbx (I think that was Matt who posted above). I’m using meetme conferences on a dedicated Asterisk box with a Digium 410 card.

Matt, how did you enable app_conference from within freepbx? I used the CONFIG_HZ=1000 + disabled RTC trick for my xen VMs in the past, but it doesn’t seem to work with asterisk 1.4. Thanks!

Matt,

That’s good to know. Thanks for sharing!

Greg, I am using app_conference in my xen voip servers since last year with really good results, i did even change 2 lines in the freepbx code to make it work with it, being able of create/remove conferences from the admin site.

Nevertheless, i did not test it under asterisk 1.4.

cheers!

This is good stuff. I’ve known that this was possible for a while now, but I’ve never had a specific answer for people when it comes up in FreeNode #asterisk . I do now. Cheers!

Aha! That’s good to know. I have since migrated onto dedicated hardware so I can install a PRI card, so the issue is academic at this point. But it is useful to know should I ever decide to migrate to a cluster environment.

Hi there, search for ztxen… it’s a clone of the ztdummy module that uses the kernel 2.6 tick timer (1000Hz) instead of RTP

This means you can run a pseudo zap chan for meetme inside a domU (i am doing so successfully!)
