Hi Jon,
The only Cisco supported Attendant Console for CME that I know of is Arc Express. Have a look;
Call Manager Express Compatibility
Arc Express 1.3 passed Cisco IVT (Interoperability Verification Testing) against Call Manager Express 3.3 in March 2006
Arc Enterprise is a feature-rich attendant console application for Cisco Unified CallManager. Arc Express is a scalable, modular application for Cisco Unified CallManager Express. Arc Enterprise and Arc Express are now available worldwide through the Cisco price list to customers and all Cisco IP Communications Specialized Partners.
