Not all calls have a real conversation. When diio detects that a call had no useful content — voicemail, wrong number, rejection, or unusable audio — it marks it with an error status and does not include it in metrics. This prevents contaminating the history and reports with failed attempts.
Error causes diio detects automatically
Voicemail. The call went to voicemail without a real conversation.
Wrong number. The call did not connect with the expected person.
Call rejected. The counterpart hung up without answering.
Rescheduling request. The counterpart asked to change the date during the call.
Inaudible audio. The audio file could not be transcribed due to low quality.
Very short transcript. The conversation was shorter than the configured minimum threshold.
Playbook not found. diio could not identify which playbook to apply to the call.
What to do based on the cause
Very short transcript.
Inaudible audio. Upload a new higher-quality audio via WhatsApp (if you have the recording available).
Playbook not found. The Settings Admin can review the active playbooks assigned to the team.
Voicemail / wrong number / rejection. No action needed in diio. This is the expected behavior for calls without a conversation.
