Is there any way to find out who has NOT recorded a Self Identification Message. Some file in a directory or report or someplace on the web management.
On a windows server you can navigate to C:\ProgramData\3CX\Instance1\Data\Ivr\Voicemail\Data and check if a file called self_id_prompt is present in each of the extension folders. The ones that do not have means they have not recorded their message.
In linux the path is /var/lib/3cxpbx/Instance1/Data/Ivr/Voicemail/Data
