I have some question on unity:
1, For configuring call transfer options on the User menu, there are two transfer type, that is 'Release to switch' and 'Supervise transfer'. I know Supervise transfer let unity play greeting when the phone is busy or noanswered, but how about 'release the switch'? Does it always loop the call to Callmanager or let caller listen the busy ring? Does it mean if I want the caller can hear busy and unavailable greeting, I must choose 'supervised transfer'?
2, I have setup a unity connection but I found there are many options cannot be changed in transfer option, such as 'Ring to wait For', it just is 4 times. Can I change that?
