Why does a call disconnect after one or two rings and how do I fix it in MyOperator?
⚡Quick answer-
Early call drops (0–2 rings) usually mean one of four things:
- No valid call flow at the current time,
- Account/plan suspended or credits exhausted,
- Routing to an empty queue or all agents unavailable, or
- A policy block (blacklist, geo-restriction, caller-ID rule).
Follow the checklist below and confirm success with a test call.
When should I use this guide?
Use these steps if callers report “it rings once, then hangs up” or your Call Logs show Rejected / No-flow events.

4 — Check routing & agent availability
Item | Where | What to do |
Department empty? | Manage → Departments | Add ≥ 1 Available agent |
Agent status | Users → Status | Turn Available, Take Calls ON, disable DND |
Forwarding number rejects? | Users → External No. | Make sure device accepts unknown CLI |
Concurrency | Numbers → Limits | Raise cap or shorten wrap-up |
Alt text: Department/Queue Assignment
Alt text: Agent Status
5 — Policy / limits that auto-drop calls
• Blacklist / spam filter – Settings → Policies → Blocked Numbers.
• Geo-permission – Numbers → Inbound Settings → Allowed Countries.
• Caller-ID rule – Reject anonymous CLI if policy enabled.
• Compliance prompt missing – Mandatory consent/DTMF enabled but no audio file attached.
6 — Network / PSTN checks (less common)
• Carrier outage – monitor multiple caller samples within 30 min window.
• SIP PBX rejects – look for 4xx/5xx in PBX logs; disable SIP ALG and open RTP 16384-32768.
• SSL inspection – if SIP/TLS 5061 or webhook callbacks in use, bypass SSL inspection for MyOperator subnets.
7 — Confirm it worked
✓ Test call during in-hours reaches IVR within 2-5 s and continues ringing/queuing.
✓ Call Logs show Connected or IVR Reached (no Reject).
✓ Test off-hours hits voicemail or fallback (doesn’t drop).

Symptom | Likely cause | Where to check | Quick fix |
Drops immediately; no log | Suspended plan | Billing | Renew plan / add credits |
Drops after 1 ring | Missing IVR | Call Flow | Add IVR or fallback |
Drops in Dept A only | All agents DND | Depts; Users | Set at least one Available |
Hidden numbers drop | CLI policy | Settings → Policies | Allow anonymous CLI |
Overseas callers drop | Geo-permission | Inbound Settings | Enable target country |
Only 2nd call drops | Concurrency cap | Numbers → Limits | Increase channels |
PBX rings then ends | SIP ALG / RTP blocked | Firewall logs | Disable ALG; open RTP |
