It appears that compound announcements (system recordings which have been strung together) cant be used as Remote Announcements in either Follow Me, Ring Groups or Agent Announcements in Queues. The Queues / Agent Announcements section actually tells you that you have compound announcements defined and to basically be careful not to use them, but Follow Me and Ring Groups do not.

If you try to use a compound announcement, defined in system recordings, in either of these the system will try to find the corresponding file, fail, and drop the call. Shown here :-

Compound announcements can successfully be used as caller Announcements in each of the places I have tried (Meet Me, Ring Groups & Conferences)
