asterisk users - Mar 2016 - conference call stuttering / clocking issue (?) - ESXi virtual environment

Title says it all - for the time being I am stuck deploying Asterisk in ESXi .
We are also looking at Proxmox for our next round of servers..

Everything works fine except conference calls - very stuttery , have tried a few
different codecs.  I assume this is a granular clocking issue , and wondering if
anyone has anything I could try to fix or mitigate the problem in ESXi
environment .

We have freepbx (asterisk 11 chan_sip) and test environments asterisk 13.7/8
pjsip .

Thank you again,


Kevin Long

One of the things you can do is google "app_konference". It
doesn't require
a clock source and is a very good application. I've successfully been using
it for years and have had no problem with 100+ users in a single conference.

Thanks John,


For anyone reading this using FreePBX - simply switching the default conference
app from MeetMe to ConfBridge seems to be a drastic improvement, have not stress
tested but running a conf now with no stutter on Confbrdige app.

Cheers,

Kevin Long
