I have installed Unity to work as AA (AutoAttended) and voicemail. Now in case of AA, unity is able to route the calls to only those extensions which have subscriber in the Unity. Unity is integrated with Callmanager. Callmanager has 1000 extensions whereas unity has just got 200 subscribers licences. So now if someone from outside calls the company AA and the caller dials an extension which does not have a corresponding subscriber, then Unity complains that "I did not recognize that extension".
Now, is there someway to route all unknown calls from Unity to Callmanager?
