What happens if the line is busy, engaged, or there is no answer when receiving a Voice API call on PSTN endpoint?
- Voice API
- Outbound Calls
- PTSN Endpoints
When Voice API makes outbound call to PSTN endpoint, by default Vonage will ring the number for 60 seconds. If the end user or their voicemail does not pick up the call, the call will be canceled by Vonage.
