The System Configuration Guide for CUC is not particularly clear on the CSSes that must be configured for functionality. 

The Inbound CSS is for calls that CUC makes, like Notifications and MWI (for SCCP intergrations)

The Rerouting CSS and Out-Of-Dialog Refer CSSes are used for calls that flow into CUC from CUCM but then flow back to CUCM.

Make sure all three are configured, and reset your trunk. Let us know how it goes.
