Answer

Grayed-out fields in the Telephone Paging plugin can mean that the plugin has encountered an error. It may not be able to find the correct required components (for example, a uniquely named Paging Router, POTS/Softphone Controller, and Loop Player).

The plugin may also be looking for a subdirectory that does not exist. Typically, the plugin will log an error in the Debug window. The sample design, as provided by QSC, looks for Audio/IVR. That is where the typical IVR .wav files should be placed. If that directory does not exist (with files), or if a non-existent directory is configured, this issue will occur. This can happen when the plugin is copied from a different design where the defaults were changed (other than the sample file).
