Before starting to troubleshoot ECE issues, it is important to know the ECE version and Engineer Specials installed, collect all ECE services logs, understand the Deployment Model, the call-flow, the messaging flow, and the configuration, and understand the customer’s intent for the flow of emails and chats.
