I have an android and iOS app and I am looking to integrate a SIP/ VOIP SDK such that users on the app can make voice/video calls to another user on the app.
This is a hybrid ios-android app built in react native.
As outcome, I would like the following:
Testing if the calling functionality works for both android and ios
Pricing to give Twilio/Zoom (or another 3rd party SDK) based on the services uses
Server Logs understanding how many users have used this functionality, how many minutes, etc
I would also like the source code post the integration.
