Frequently Asked Questions
Can React Native support VoIP calling with CallKit?
Yes. React Native bridges to native iOS CallKit via react-native-callkeep or react-native-voip-push-notification packages. This enables background call handling, native call screen UI, and correct audio session management — critical for App Store compliance.
How does SIP work in React Native apps?
React Native VoIP apps use a native SIP library (PJSIP, linphone SDK) exposed via a custom bridge module. The JS layer handles UI and state; native SIP stack handles signalling and media. This approach gives near-native call quality without sacrificing JavaScript flexibility.
React Native vs Flutter for VoIP mobile development?
React Native is better if your team knows JavaScript and you share code with a web dashboard. Flutter is better for highest UI performance and single codebase with less bridge overhead. Both support VoIP; we have expert developers for both.
How much does a React Native VoIP app cost?
A production React Native SIP dialer app (iOS + Android) typically costs $15,000–$40,000 depending on features: registration, call history, contacts, voicemail, and CallKit/ConnectionService integration. Our dedicated developers at $25–32/hr complete this in 8–14 weeks.
Can React Native apps be rejected from the App Store for VoIP?
Apple reviews VoIP apps carefully. Using CallKit is mandatory for any app that receives push-to-wake calls. Apps using background audio without CallKit are regularly rejected. Our developers know Apple's VoIP policies precisely.
What's the difference between PJSIP and linphone SDK for React Native?
PJSIP is more configurable and widely used in enterprise — ideal if you need custom codec support, complex NAT traversal, or SIP SRTP specifics. linphone SDK (liblinphone) offers a higher-level API with built-in video and easier UI integration. We use both depending on project requirements.
