Kind of all over the place with MOH settings. Remember that CO trunk group MOH settings will override any phone or other device music setting, so having FB set on the phone means nothing unless the trunk group is set to Use Next Device's Audio Source.
Looking at your trunk groups, MOH should work for 92001 but not 92002 (unless you have an external source plugged into the controller). Without an external source, 92002 will always hear silence.
As a general rule, Audio on Hold for Transfer Announcement should always be Silence. Otherwise you'll hear a ring burst or snippet of music on transferred calls. Audio for Calls Holding for this Device is only for Mid Call Features, so that shouldn't matter.
You updated while I was posting... yes, replacing the music file will reset the music value.
