What are the ring setting set to on CUCM?

Is the volume on the phone up?

I had this exact same issue.  It turned out to be Do Not Disturb.  Since this is not a softkey, and isn't controllable throught feature control sets, it must be set as a lince presence.  Best as I can figure, DND was set as a line presence (through button templates) enabled by the end-user, and then removed from the line presence, leaving no way to disable it from the phone.  Tested in lab and replicates the behavior exactly of a short sound, and then nothing.  Could be different depending on your DND settings in CUCM.  You can turn DND off directly from the phone config page.  Very different behavior than the previous 69xx and 79xx series phones for DND.

Hope that helps someone!
