I'm working on a React Native app (tried both Expo and React Native CLI) for internal use by our company employees only — it won't be distributed via the App Store or Google Play.

🔧 What I'm Trying to Build: We want to enable our call agents to:

Make calls to customers numbers from within the app (e.g. for order confirmation).

Record those calls for internal auditing and quality assurance.

This feature is crucial for our order confirmation workflow.

✅ Requirements:

The app will only be used internally (we control the devices).

Android support is required, iOS is a nice-to-have.

No requirement to publish to Google Play or App Store.

Call agent should be able to tap a button to initiate a call and the app should automatically start recording the conversation.

Any advice, code examples, or suggestions from folks who’ve done something similar would be hugely appreciated!

Thanks in advance 🙏
