    Just for fun I decided to test once again the functionality of Mediation Server role run on virtual environment. The role was installed on Windows 2008 with Hyper-V. I tested it on host with AMD and another with Intel Xeon CPU.

    AMD based server was total failure - very bad voice quality (although the role installed and run just fine.) The Mediation server installed on Intel Xeon server, however, is performing just like dedicated hardware. We tested it with four simultaneous calls, SimulRing, 3-Way etc. with excellent voice quality and performance.

    This result shows that indeed Mediation Server role on Virtual host can be used for test environment. I'm planing to go even further - since we will deploy trunk with unlimited local calling for our base service, a second Mediation role (on virtual host) connected to unlimited LD trunk could be used. The base trunk (hardware) will carry 40 simultaneous and the LD -six. The Dial Plan will determine which mediation server should be used based on the dialed number.

    Of course, using Mediation Server role in virtual environment is not officially supported (including on R2).

    Virtualisation of OCS and specifically mediation server is indeed not supported, but check these guys www.startready.com

    They deliver an OCS appliance fully virtualized including mediation server on Hyper-V with the ability to have OCS up and running much faster than a normal system integrator install. They have a Microsoft background and a lot of expertise around virtualisation.

    Up until recently, that is - before W2K8 and HYPER-V, people were using Virtual Server 2005 and/or Virtual PC i.e software virtualization. This is why the voice performance was poor. With barebone hypervizor as HYPER-V the game has changed.

    "Mediation Server role in virtual environment in not officially supported" only means - you will not receive support from Microsoft directly.
