[Freeswitch-users] VMWare voice quality

I have been running FreeSWITCH on a VM ever since I got involved in the
project. It's been almost a year now. I didn't do anything special - it
works fine. I get audio problems if I go over 10 or 15 simultaneous calls.
This is on the following setup:
VMWare Server 1.0.6 and VMWare Server 2.0 (2.0 sucks, btw </rant>)
Dell Precision 360 (Desktop)
Pentium 4 2.66Ghz
2.5GB RAM (512MB allocated to FS)
Fedora Core 8, 220.127.116.11-42.fc8 stock kernel (a bit old)
7.2K 80GB hard drive
Yes, fancy machine I have, huh?
This is my normal day-to-day workstation as well as my VMWare Server. It
works fine, I got occassional missed heartbeat alerts and timer sync
notices, but they're rare.

If anyone figures this out please post it to this thread. I am working on a
wiki page for the VMWare appliance and I would like to be able to inform
people on how to handle this situation.
Also, IIUC, those running VMWare Fusion on Macs are not experiencing this,
correct? What about those using a hypervisor like ESXi? Any known issues?
