Greeting (compression ratio?)

Hello, I have what is possibly a quick question. What compression ratio does asterisks like for background music, or greetings… ? I recall uploading a wav file a while back and somehow it was rejected or caused a problem with the program… due to it not being a format that worked well with asterisks…


Usually Asterisk work with WAVs 8Khz,16PCM MONO files.

Thank You :smile:
