• Outbound Calls
• PTSN Endpoints

Answer

When the Voice API makes an outbound call to a PSTN endpoint, it will ring the number for up to 60 seconds by default. If the end user or their voicemail does not answer up the call, the call will be canceled. If using the ring timeout feature, you can configure when the call will reach timeout status, and terminate.
