I'm using freeswitch in production environment running on ESXi . I have
no issues with voice /probably because simply i leave the media to flow
between endpoints/ . Performance is amazing and i'd recommend this setup
it is important though when you set your VM on ESXi to set in advance
the number of CPUs. Changing # of CPUs later might affect your
performance. My recommendation is NOT to use VMWARE server on top of
other OS. ESXi as hipervisor is linux in its core that provides you
with enough access to the HW and nothing more so the overhead is as
minimal as possible /while this is not the case fro VMware server - it
needs underlaying OS and so on/.
I hope this info helps.
If anybody is interested i'd be glad to share me experience on his matter.
