Do you have a music or audio source? (ie: cd-player). Then you can wire the speaker output of that to an auxillary port off your PBX, if no aux port is available, you can wire to a single analog port and enter that port in your customer parameters features screen. Then in the COR screen of your general user community, turn on MUSIC ON HOLD = YES.  Hope this helps...

Can you explain a little bit more when you say wire  it to a single analog port or aux port. Are you referring to the acutal wire on the speakers to the board where there is a live port on the wall where the switch is. Sorry to ask so much question but this is kinda new to me... Thanks for all the help.

From your CD/audio source player-take a speaker cable out, split the pairs +/- and run that lead to your MDF (Main Distribution Feed) of your PBX where your line cards from your PBX terminate. Find a spare analog port (li conf sta) on your command line to find port. With your punch down tool, punch the the pairs down on the frame. (And then with a "butt" set (if you have one) tap onto line and confirm audio). Then you can program the software in the PBX. Hope this helps...
