Hey, ​@Milly25 I’m sharing a KB article here to help with this. 
There are two options here - either as an admin or a user. Not sure which category you fall under. 

If this doesn’t do the trick, please circle back with us and we’ll dig in a bit deeper. 
Setting up your hold music

On the RC phone app hit the Hold Button in the middle

to modify what music is played while on hold go to the Users profile/Phone/Hold Music

Select the music type and music

to manage this setting for all users. create a user settings template and apply the template to everyone you wish to have the same settings.

Heck yeah, ​@john_thephoneguy!
Where did you come from? 😊
Thanks for lending a hand here.

And if you really are the phone guy, we should maybe talk - I might need a guy with your skills around here!
