Which licence is required for 'On hold' music?

Hi there,

Does anyone know which license would be required for music that is played when someone is placed on hold on the telephone?

Thanks

Hello,

For some reason, the music licenses do not cover on-hold use.
Also, the rule stating you can’t use a music track as is would prohibit it, unless you add a voice-over that keeps repeating “please hold” or something like that.
