Since ECM leverages on the dialing capabilities of Cisco Outbound, each voice campaign in ECM is mapped to a corresponding campaign in Cisco Outbound. Therefore, So all technical, dialing-related details such as dialer modes (Predictive, Progressive, Preview), call scripts to be attached with an IVR campaign or CSQs/Skill groups to be linked with an agent-based campaign are handled at Cisco side while ECM keeps the campaign configuration simpler for non-technical supervisors and administrators.

Note that one Cisco campaign can also optionally be shared by several ECM campaigns, who have the same call flow and/or agents to handle calls but run in different schedules (start, end timings) or have different prompts to be played.
