Knowledge Base & Operational DocumentationWhy Does a VoIP Call Keep Ringing After Someone Answers?
An answered call may continue ringing on other phones if shared line appearance, simultaneous ring, or call pickup state does not synchronize promptly. This can confuse coworkers and lead to duplicate answers.
What to check
Check endpoint registration, shared line and ring group configuration, call state logs, network delay, and device firmware. Compare behavior across handset, softphone, and mobile app.
Recommended next step
Correct shared call handling and verify state updates across all devices. Test answer, hold, transfer, and missed-call behavior after configuration or firmware changes.
