Based on the intelligent voice call, combined with customer management module, task management module and statistical analysis module, an accurate, standardized and automatic customer marketing system is implemented to cover all stages from the screening of target customers, to the execution of marketing voice calls, to the feedback of intention result and to the adjustment of screening rules, which effectively improves the marketing accuracy and reduces the marketing cost.
