I have CUCM7 running on VMWare Server 2 on my Windows 7 machine. Not a half bad desktop and I've been watching the CPU utilization and memory and it's not getting killed. I have a strange problem appearing on my Cisco switch. It says there is a duplex mismatch with my desktop computer, but more specifically the CUCM7 vm. My switch says CUCM is running at half duplex, yet my desktop and the VM says it's running at full duplex. I would guess that is whats causing the delay in call routing every other time you dial another extension. Has anyone run into this before? The only things I can find on the internet is referencing VMWare ESXI, not VMWare Server or anything. Any help is appreciated.
