"If they have a SX-200 MX in a hospitality environment, then they most likely have 12-20 voicemail ports (assuming it was engineered properly, thats a big assumption I know). So setting this up should be fairly simple. You put some VM ports in a Recording Hunt Group, give it an extension and set the options, then setup the RAD Group in form 49, record RAD, and set a couple options here and there, and put the extension in the Wake-Up routing of the call rerouting for the tenant used for the rooms (well, it sounded simple in my head before I typed it out).
Remember that the 200 can only make one wake-up call per RAD port at a specific time (not a restriction when using MOH for wakeups), so if it has to make 300 wake up calls at 6:00am and you only have 2 RAD ports with a 30 second recording on each one, the math says some people are not going to get up on time! A good rule of thumb I use is have a ratio of 1:20 rooms to RAD ports, and keep the recording under 15 seconds."
I cheated and copied this from an answer for elsewhere, but I think it should help in clarifying your friend issue.
