Asterisk running on VMware

Does anybody have experience or running Asterisk on VMware(?) - specifically the latest ESX...?

I've got a proof of concept working but am reticent to roll it out without a bit more reassurance! I keep hearing about problems with timing...?

Anybody done it?

Solution 1:

It works but there are applications that depend on an accurate clock that need some special attention, for example conference bridging. A good test is to install asterisk + zaptel and compose a test dialplan for a conference bridge. Connect to the bridge with two phones and listen to the audio.

Solution 2:

Several years ago we ran it in a VM on a basic Pentium 4 host - and it was no good. Voice was choppy and cut up. We installed it natively on the P4 (I think it was a 1.6) and it was all good.

Since then we haven't installed it on any VMs, but I've heard from others that just as long as you assign it enough resources it should be fine.
