Hello,
I’m trying to upload custom ringtones, through the RINGTONES tab in the DIGIUM ADD-ONS of FreePBX.
After reading this link:
I’m using SOX line to convert my ringtones from WAV to SLN
sox -V myfile.wav -t raw -r 16000 -s -2 -c 1 myfile.sln
Conversion occurs without warns or errors.
Then when I try to upload the file, I ALWAYS GET this message:
“Uploaded file is not valid.”
Then I see it in the list of available Ringtones in any Digium phone that has reconfigured, but it won’t play.
Please help!
