| Hi I have never had to add external MOH to an OXO, but from what I can gather you will need a daughterboard AFU-1. Then to set the option from PM5, go to System Miscellaneous > Messages & Music > Music on Hold. If not then other users with more hands-on experience will no doubt be along to advise further.* Kind regards. *Edit: Especially with regard to how to wire your audio source to an RJ45 port!
