I'm very new to CUCM. We are using just the basic call queue/hunt groups that come with CUCM 9.1. I am trying to set up the Music On Hold Server Audio Source to run a Welcome message as the Initial Announcement and the Periodic Announcement to run Wait In Queue Sample. I've tested an audio source with a test hunt group (hunt pilot configured for the correct Network Hold MOH Source & Announcements) and I get an initial message "please wait while we transfer your call..", but I never get any periodic messages - after the max queue wait time, I'm moved into voice mail (which is what should happen).
I can see from the Music on Hold Audio File Management that some files are in use (like the SamepleAudioSource I'm testing with), and some in Translation Complete.
How can I get the periodic messages to work - I'm at a loss.
