If my system is setup with teh following DID number range 617 302 1XXX
and I only have DN setup for 617 302 10XX when someone tries to call a number with my range but that has not been allocated they get fast busy 617 302 1800 What I would like to try and do is create perhaps a CTI RP with DN 18XX and put a Call-Forward-All on this to voicemail, and try to get Unity to say somethings like this numebr is not available at this time .....I am not sure what standard messages unity has. Does anyone have any ideas on this.
