Call Manager over DOCSIS - Best Practice QoS

I am going to be configuring a UBR10000 supporting DOCSIS 3.0 modems.  I will be using channel bonding.  At the Headend there will be a Call Manager installed.   IP Phones (SCCP) will be co-located with the Cable Modems.  The network looks like this:

Call Manager <-> Ethernet <-> CMTS UBR10000 <-> RF Plant <-> Cable Modem <-> Ethernet <-> IP Phone.

So my question is, what are the Best Practice recomendations for QoS to support the VoIP and Call Setup traffic going across the RF plant?  Specifically I'm looking for CMTS configuration suggestions and Cable Modem config file suggestions.
