I am having an issue with AC for Call Manger Buusiness Edition 612 in that whe nI try to open the application, I get "Error communicating with Server" message. I have full ip connectivity to the server. I have configured the AC app user, auth user and attendent console user and given them all the relevent permissions. I am not using a pilot point as there is only one phone and 1 extension. Has anybody had issues with AC and this version of Call Manager?
