📞 Test Call Transcript History

The Agent Builder keeps a history of test calls so you can review past conversations and compare agent behavior over time. View a list of previous test calls with timestamps and outcomes, open any past call to read the full transcript, and quickly spot patterns or regressions when tuning prompts.

📞 Call Settings

Control how calls work:

Setting	Description
Max Call Duration	The longest a call can be before it ends automatically ⏱️
End Call After Silence	Hang up if nobody talks for a while
Ring Duration	How long to ring before giving up (for outbound calls)
Denoising Mode	How background noise is handled: cancel noise only, or cancel noise + other voices talking

Let callers press buttons on their phone to interact:

Setting	Description
Allow User DTMF	Turn on keypad input during calls
