I currently have CCM6.1 setup in a lab using VMWARE. I have 2 phones setup and registered to Call Manager. I have 1 CSS and 1 Partition. Both phones are part of the CSS. The phone DN's are 5001 and 5002 and are assigned to the same partition. When I try dialing one of the phones, it will ring, but once I pick up, the dialing phone hears a Fast Busy. Here is an example. 5001 dials 5002. 5002 rings and picks up. 5001 will then hear a fast busy and 5002 will drop the call. This happens if I dial from 5002 to 5001 as well. Any insight?
