I need to use azure cognitive services (speech to text) behind a corporate firewall. The speech to text batch processing has a callback from azure notifying once the process is complete. (https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/batch/csharp) - see webhookreceiver.cs
Does anyone know what azure cognitive services IP addresses that needs to be whitelisted on the corporate firewall so that i can receive the callback requests from cognitive services?
