How does voicemail work in MyOperator, and how do I set it up?
⚡Quick answer -
Voicemail automatically plays your recorded greeting, captures the caller’s message, and stores the MP3 plus an optional transcript in a shared inbox. You can receive Slack/email alerts, auto-assign messages, and call back in one click.
When should I use this guide?
Use this checklist any time you need to
(a) Add a new Voicemail node to a call flow,
(b) enable voicemail outside business hours, or
(c) troubleshoot why messages are not being recorded.
1. Prerequisites and limits
Requirement | Minimum value |
Audio greeting | MP3/WAV ≤ 25 s, ≤ 1 MB |

3. Set up voicemail in the UI
A. Add or edit a voicemail Node
- Log in as Admin → Call Flows → select your flow → Edit.
- Drag the Voicemail node directly after each Ring Group and in your After-Hours branch.
- Greeting:
- Upload MP3/WAV or choose Text-to-Speech.
- Keep the file under 25 s; announce recording if required by law.
- Recording settings:
- Max length:
120 s(edit as needed). - Silence timeout:
3 s. - Click Save & Publish; a green toast, “Flow updated,” confirms success.
B. Update the voicemail email (alert recipient)
- In the same Call Flow editor, click the Voicemail node you want to modify.
- In Email recipients, enter the new destination address (e.g., support@example.com).
- If multiple Voicemail nodes exist (Sales, Support, After-Hours), repeat steps 1–2 for each node.
- Click Save on every edited node.
- Click Save/Publish (top-right) to apply all changes. A toast “Flow updated” confirms success.
4. Expected results & KPIs
• New messages appear in the Inbox → Voicemail (or your alert channels) within 2 minutes.
• Baseline targets:–
- Voicemail capture rate ≥ 99 % of unanswered calls
- First response time ≤ 1 business day
- Callback completion rate ≥ 90 % within SLA
Verify: Analytics → Call Logs → Outcome = Voicemail and compare with Missed Calls.
5. Troubleshooting
Symptom | Likely cause | Fix |
No recording saved | Voicemail node missing on some branches | Add a node after every Ring Group and After-Hours branch |
Silent/empty file | Silence timeout too low | Increase to 5-6 s; remind the caller to speak |
“Mailbox full” error | Org quota reached | Delete old files or raise the retention limit |
Transcription garbled | Wrong language selected | Set the correct language; verify audio quality |
Alerts not delivered | Wrong email / Slack webhook | Re-enter destination; check user permissions |
When voicemail does NOT work?
• External recording laws prohibit silent recording; they are disabled in restricted regions.
• If you enable auto-attendant only routing with 100 % agent pickup, voicemail never triggers—use at least one Voicemail branch for redundancy.
