I have a client running Windows 8 PCs on their LAN and want to use UM with their MICS/CP100. I have UM 5.0 working with XP Pro and 7 Pro elsewhere but never tried Windows 8.If so will 64 bit OS still work with UM 5.0? Is there a latest Avaya patch or is 5.0 done and over? Their not ready to bail on the ol' MICS, but would like UM.Any help or suggestions is greatly appreciated!
