I had a customer requirement wherein they want to disable direct transfer without consultation on monitored buttons. This is common in a receptionist phone that has a side console.
To make it direct transfer WITH consultation, enter this command under the telephony service.

Consultative Transfer With Direct Station Select
Direct Station Select (DSS) is a feature that allows a multibutton phone user to transfer calls to an idle monitored line by pressing the Transfer key and the appropriate monitored line button. A monitored line is one that appears on two phones; one phone can use the line to make and receive calls and the other phone simply monitors whether the line is in use. For Cisco CME 3.2 and later versions, consultative transfers can occur during Direct Station Select (transferring calls to idle monitored lines).
If the person sharing the monitored line does not want to accept the call, the person announcing the call can reconnect to the incoming call by pressing the EndCall soft key to terminate the announcement call and pressing the Resume soft key to reconnect to the original caller.
