I currently have a UC520 attached to my network, not as my default gateway or router. It's attached just as a network device which I set option 150 for using my router's DHCP scope.
My default gateway is a cisco 871, IP 192.168.5.1 - the UC520 CME IP is 192.168.5.7 and CUE is 192.168.5.9. I can not get office manager to connect to 192.168.5.7 - it just keeps on trying to connect to my default gateway 192.168.5.1.
Has anyone tried connecting to a UC520 that is not their default gateway using Office Manager?
