## Chapters

1.   0:00 When an agent doesn't behave the way you expect, start by talking to it. Talk opens a test call right in your browser. 
2.   0:09 Every real call keeps a full record. Here's one of Delivery Feedback's calls. 
3.   0:15 The transcript shows what the agent said and what it heard. Wrong words here usually mean the transcriber, not the prompt. 
4.   0:25 The timeline lists every step with its timing: when the greeting played, how long the model and the voice took. Slow steps stand out here. 
5.   0:36 Logs for this call opens everything the call logged, for the details behind each step. 
6.   0:43 Logs also keeps your webhook deliveries and API requests, so you can see what your systems sent and received. 
7.   0:52 Found the cause? Change the agent and save. Versions shows what each change did, and restores an older version in one click. 
8.   1:01 For a quick diagnosis, ask Composer. It reads your recent failed calls and explains what went wrong. 

Talk to the agent, read a call's transcript and timeline, check the logs, and roll back a change.
