Music on Hold
Music on hold is the music played to individuals on hold or during
conference calls while conference members are waiting for the call to
begin. The Asterisk Appliance 50 comes with a default group, or class, of
sound files which can be used for music on hold. Click Music on Hold
and then select the default class to see the list of default sound files.

If you think the default music is acceptable, but you’d like to give your
system a more customized feel, you can also upload your own music or
sound files. Each file uploaded must be less than 10 megabytes, in 8KHz
mono, and in ulaw, alaw, g722, or gsm format. Not sure how to convert
your audio to an acceptable format? Linux users should try the Sox utility,
and Windows users should look into Audacity. Any conversion program
is acceptable as long as the file meets the upload criteria.
