Silence Detection and Automatic Voicemail Termination
When the voicemail system detects no valid speech or audible input for five consecutive seconds, such as during silent robocalls, it should:
- Play a prompt informing the caller that no audio was detected.
- Allow one additional attempt to provide a response.
- Automatically terminate the call and discard the voicemail if silence continues
Business Significance:
This feature would prevent silent or automated calls from generating unnecessary voicemail recordings and consuming billable toll-free minutes. It would reduce operating costs, minimize unwanted voicemail traffic, and improve the overall efficiency of toll-free number management.

We consistently get voicemail messages that have no sound, and last several minutes, some more than 10 minutes! We assume these are spam calls, and we block the number, however, it consumes valuable resources.
