Well, I found this during on of my test calls:
[2015-12-08 16:22:20] VERBOSE[5466][C-000000f7] app_voicemail.c: Recording was 1 seconds long but needs to be at least 30 - abandoning
This makes no sense, my settings don't have a 30 second minimum. in fact, when I go into Voicemail Admin, something like 90% of the text boxes are blank. Is that normal?
