Asterisk Wideband Music on Hold
Asterisk Wideband Music on Hold
The default music on hold included with Asterisk leaves somewhat to be desired, and getting high quality replacement music in the correct formats can be a challenge. I have not managed to figure out how to convert to G722, but you can easily convert to the native Asterisk SLN format with the following commands:
Please note that I run Ubuntu 14.04 server
Step 1: Get the source music file (I prefer MP3 since they are easy to work with)
Hint: Search on youtube with a creative commons licence
Step 2: Copy the file to your Asterisk server
I use WinSP to copy filesStep 3: Install the necessary conversion tools
apt-get install mpg123 sox
Step 4: Convert the MP3 to a high quality wav file
mpg123 -w vivaldi.wav vivaldi.mp3
Step 5: Convert the wav file to a high quality sln16 file
sox vivaldi.wav -t raw -r 16000 -c 1 vivaldi.sln16
Step 6: Copy the file to "/var/lib/asterisk/moh" and reload moh in Asterisk
