If I need to install the IPCCE on a non Cisco harware (HP or IBM server), I heared that there is a registry file need to be run that will modify the registry to allow the IPCCE software to be installed on the hardware.
Can anyone advise for this file?
VMWare allows you to create a virtual Linux box abstracted from the underlying host and you can then insert the CUCM installation DVD and it will install. The host can be running a range of operating systems - I have used Windows XP, Windows 2003 Server and VMWare's own operating system on an ESX server.
The installer knows it's a VMWare abstraction and does not do the normal hardware checks. The process could not be any easier.
There are many blogs out there with movies that guide you through the process of installing. Try this URL and watch the video.
Since I just helped a colleague install CUCM 7.x on an ESX 3.5 server today and I found this simple guide to the post-install steps, with a movie you can watch, I'll provide the URL.
