20 VMs is too many. I wouldn't run sipX in this scenario.
I was talking about max 3-4 VMS on a ESXi server with 2 GB RAM. I believe that should befine From: Simon Stockdale [mailto:[email protected]] Sent: Friday, 19 June 2009 3:12 a.m. To: 'James R'; 'Yakout Esmat' Cc: [email protected] Subject: RE: [sipx-users] virtual sipX Are you running much else on the VM box? I have a similar (if not identical server) running a number of non-SipX VMs and I do often notice that if one VM goes rogue and spins on CPU it can disrupt other VMs. This often manifests itself as a 2-3 second pause on the other VMs. We have limited the resource of the sometimes rouge VMs but it still causes the strange pauses. FYI - we are running ESXi 3.5 with about 20ish VMs running on that box with a mix of local storage and iSCSI storage.

We initially used it for lab testing, but we are now doing a production trial in a virtualized configuration. We are using good hardware (Dell 2950 with 32 GB RAM, 2 quad core processors etc..). I can't speak to the NAT issue since we are not a typical deployment. We are only using the ACD function right now. For the Virtualized configuration we are using VMware ESXi Hypervisior installed directly on the server, so sipX has more direct access to the hardware without an additional underlying OS managing the sipX virtual machine. I can report back as we scale this trial. We have not had audio issues in our lab testing.. we will see what happens in the production trial with the media quality.

I know from my past experience that VoIP and virtualisation do not mix. We have tried several times to run Asterisk, with its different flavours and distros, as a VM within a VMware server unsuccessfully. Every time we run into voice quality issues, clipping etc....
