Where exactly can I control which MOH file does a analog phone (controlled by a gateway) receives?
The phone must have a MOH media resource available for this to work, but since analog phone do NOT have "User hold MOH Audio Source" field, how do they know if they should play audio source #1 or audio source #4?
My best guess that they default all the way to the Clusterwide Service Parameters
Is that correct?
Meaning there is not a way to change ONLY ONE analog phone's MOH
On the other hand, the only way to disable MOH is to remove the MOH media resource.
I guess I answered my question while I was writing the previous post and remembered to check the Common Device Configurations and if I'm not wrong the priority order (lowest to higher) for MOH Audio Source at least is: Service Parameters, Common Device Configuration, Device, and/or Directory Number.
