### Answer Based on your logs, the call is connecting but ending after approximately 8 seconds (from 17:56:50 to 17:56:58) . The webhooks are firing correctly -

call_started

,

call_ended

, and

call_analyzed

are all triggering and receiving responses [(1) ]() . Here are potential causes for calls going blank and ending quickly: Agent Configuration Issues: 1. Begin Message Delay - Check if

begin_message_delay_ms

is set too high. This delays the first message, which could make the call seem blank [(2) ]() [(3) ]() . 2. End Call After Silence - The

end_call_after_silence_ms

setting ends calls if users stay silent after agent speech. The minimum is 10,000 ms (10 seconds) , default is 600,000 ms (10 minutes) . Your call ended at ~8 seconds, which suggests the agent might not be speaking at all. 3. Max Call Duration - Check

max_call_duration_ms

. The minimum is 60,000 ms (1 minute) , default is 3,600,000 ms (1 hour) . This shouldn't cause an 8-second disconnect. Recommended Actions: 1. Check your agent's response engine configuration - ensure the LLM is properly configured and responding . 2. Review the

call_ended

webhook payload for the

disconnection_reason

field - this will tell you exactly why the call ended [(1) ]() . 3. Check if your agent has a valid

voice_id

and

response_engine

configured [(2) ]() [(3) ]() . 4. Verify your webhook responses are returning successful status codes (2xx) within the 10-second timeout [(1) ]() . Can you share the `disconn

ection_reason` from your

call_ended

webhook payload? That will help pinpoint the exact issue.
