We're looking to build a SIP based softphone with react-native using [login to view URL] and react-native-webrtc. Inbound calls should be able to utilize PushKit and CallKit on iOS due to new restrictions in iOS 13, the backend for push notifications is already available just need to build out the frontend.
Needs to be a full functioning phone and phone screen should be able to hold a call, transfer a call, conference, mute, activate speaker phone, etc.
We are not married to react-native-webrtc but felt it was the most logical way to support media cross platform. If there is a better way we are open.
