After upgrading system from 3.1.145 to 3.3.5.36 When we use the Test Call function using pretty much any of the audio files, upon answering, we just hear a series of staticy sounds. Specifically the demo.wav file that has always worked in the past seems to be broken.
When a live call is placed, the audio seems to be working. Not sure if there is a new special format, or if there is something that needs to be done to get these working again.
I did download the file and play from my local computer and it played correctly. I renamed and uploaded and it still had the same problem.
