Specifications for MoH Port Connections

I've searched the Cisco Web site and documentation and can't find any information or specifications for what I can connect to the MoH port. I have a Digital Messaging System with both a 600 ohm and an 8 ohm output. Which should I use to connect to the MoH port?

The UC500 MoH port is a standard 3.5-mm mini-jack.

The size I found.

What I'm not finding is information such as:

1. Is it Mono or stereo

   

- I can fairly safely ASSUME its mono

2. When impendence does it have? Is it 8 ohms or 600 ohms or something else?

     - If I plug in the incorrect impendence source it will not work correctly. Worst case i will 'short' the UC Mother board and burn it out. or the  MoH source output amp. Best case it just won't work correctly.

Does anyone have an update for this question or should I call Cisco Support?
