a warning to all: using moh off announcement board may give unpredictable results with any tsapi cti application. the problem is, when an agent (or an user) puts a call on hold (or transfers, conferences...), system sends a csta delivered event with announcement extension number, regardless of aes settings. this creates a situation when a call is being connected to two unmonitored endpoints, trunk and announcement, and your cti application may go crazy over that. nice cls does. 
i see this problem with cm 3.0.1 and aes 3.0, don't know if it can be replicated with latest versions, we're working in our lab on that.
