We have a customer with 9 different Premier USB MOH boxes for his 9 different companies running through the PBX. The customer wanted to know if there was a way to use fewer boxes and still get providing different custom MOH audio to the PBX. I have not heard of any device that can play multiple files to multiple outputs, but I thought I would see if anyone else ran across something like that.

Replacing the PBX is not an option. The primary purpose is to reduce the number of devices and the space used on the back board.
