Faults worth memorizing — Ecosystem
Glossary
- Flow log A CloudWatch log of each block. Set logging behavior turns it on. The log group is under the instance.
- Error branch The path a block takes when it fails. An unconnected error branch ends the contact.
Mind map
Open the Troubleshooting mind map
Sister technologies
The useful habit is to name the hop, the ContactId, the counter, and the log line before you edit the flow.
Config and troubleshooting
One runbook called 'call quality' that includes Lambda timeouts.
The troubleshooting habit starts with a log line. ContactflowLogs on the instance is what lets Set logging behavior write to CloudWatch.

Integration map
Join records on ContactId. The integration map room lists the seams.
Cross-platform bridges
A CUCM calling search space is not a routing profile, but the profile is the closest idea of 'who can receive what'. A partition is not a Connect object. A UCCX CSQ and a UCCE skill group map to a queue. Precision steps map to routing criteria. A script, an Architect flow, and an Avaya vector map to a contact flow.
Future hooks
Hooks you can adopt later: EventBridge contact events, the CTR stream, agent events, Kinesis Video, Customer Profiles events, Cases, Show view, data tables, External Tool, and the flow language JSON in your pipeline. Live Sync and Agentic CX are the 2026 hooks for guided and agentic experiences.
