How can i play beep e.g. before recording a file, i want to alert the user with beep. I thought its a sound file that installs with FS (like the one comes with Asterisk installation), but i couldn't find any such file in any format under default sounds. However, i do checked and confirmed that FS plays a beep when e.g. recording voicemail or user greeting etc. etc. but it does print file name it play for beep in console logs. What am i missing here?
