Snippet: Voicemail Transcription
You will need a machine with Python installed, the SignalWire SDK, a provisioned SignalWire phone number, and optionally Docker if you decide to run it in a container.
For this demo we will be using Python, but more languages may become available.
- SignalWire SDK
- SignalWire Phone Number
- MailGun Account (For administrator notifications, https://www.mailgun.com/)
- Docker (Optional)
How this Voicemail Transcription application works
We are going to build off of our Simple IVR Menu, and add ring groups
