It is hard to believe but appears not to work correctly.
I have various sound files to be uploaded:
a. wav - 8000 Samples for second, Mono, 16-Bit (verified with Audacity).
b. gsm
c. mp3
This does not work for me
1. Goto Add Recording under System Recordings
2. BROWSE to the file to be uploaded, click Upload.
3. Click OK to confirm and wait for page reload
4. I get the message Successfully uploaded.
5. But I do not see a name of the file that was uploaded.
