We have three CAS servers and 3 Mailbox servers, all virtualized. In our test environment, before we moved from CUCM 6.1 to 10.5 we are able to at least get Exchange 2013 to answer a SIP trunk request from CUCM 6.1. Now in CUCM 10.5 we just get a fast busy when we dial the VM pilot number. Does anyone have experience with this and have a guide that we could follow?
