### Answer Yes, you can determine if a person did not pick up through the

disconnection_reason

field. When a call is initiated but not answered, the following applies: Webhook behavior for unanswered calls: - The

call_started

webhook will not be triggered when the call did not connect (like dial failed, no answer, or busy) . [(1) ]() - The

call_ended

and

call_analyzed

webhooks will still be triggered for these calls. Disconnection reasons that indicate the call wasn't picked up: -

dial_no_answer

– The number dialed did not answer [(2) ]() -

dial_busy

– The line was busy -

dial_failed

– The dial attempt failed Call status: When a call doesn't connect, the

call_status

will be

not_connected

. Important note about post-call analysis: Post-call analysis fields will not be populated for calls that were not connected or where no conversation took place. You should check whether the

call_analysis

field exists before using it. [(3) ]() So to summarize: you'll receive a

call_ended

webhook with a

disconnection_reason

like

dial_no_answer

that tells you the person didn't pick up.
