Could you build this?

No Building a reliable video calling client with native CallKit integration, low-latency live captions, multi-lens camera switching, and custom WebRTC/VoIP plumbing requires deep mobile and real-time telecom expertise.

What it would actually take: The architecture requires native iOS (Swift/Objective-C) leveraging CallKit and PushKit for VoIP notifications, alongside an AVFoundation pipeline for lens switching and camera buffer manipulation. For real-time communication, a custom WebRTC media server (LiveKit or mediasoup) with STUN/TURN traversal is needed, paired with an on-device Speech framework or Whisper streaming pipeline for real-time subtitles. Handling network handoffs, audio routing, and low-latency synchronization requires specialized real-time systems engineering.
