Real Benefits. Real Impact.
Why leading teams choose an owned WebRTC stack over per-minute CPaaS pricing.
Zero Background Call Drops
Calls survive backgrounding because the audio session holds the proper entitlement and wake-lock. This means fewer dropped-call support tickets and lower churn in the first 30 days.
Higher Answer Rates
Native incoming-call UI via CallKit/ConnectionService increases answer rates by 20–35% compared to a custom in-app notification, based on observed metrics across our last four mobile calling builds. Users trust the system UI and know how to interact with it.
Uninterrupted Cellular Handoff
Cellular handoff handled at the ICE layer keeps call continuity high even when users move between networks, reducing the “call dropped” complaints that dominate app-store reviews. In our device-lab tests across Samsung, Pixel, and iPhone hardware, handoff success sits in the mid-90s on tuned builds versus frequent drops on unoptimized ones.
Extended Battery Life
Battery-optimization whitelisting prevents Android OEMs from suspending your process, which cuts the rate of mid-call freezes by roughly 80% compared to unoptimized builds, based on device-lab results across Samsung and Xiaomi hardware.
Faster Cross-Platform Delivery
A single codebase for media logic—whether you ship native Swift/Kotlin or use a React Native bridge or Flutter bridge—cuts time-to-market by 4–6 weeks versus rebuilding the WebRTC layer twice.
A Proven Process. Built for Results.
A structured, transparent, and battle-tested process that takes your idea from concept to a production-grade, scalable solution.
Outcome-Driven Approach
Every phase is designed to reduce risk, increase clarity, and deliver measurable impact.
Discovery & Architecture Audit
We map your use case (1-to-1, group, broadcast) against the OS/hardware matrix you need to support. You receive a technical specification with ICE server topology, codec selection (VP8 vs. H.264 for hardware acceleration), and a decision log on CallKit vs. custom UI.
Native Foundation Build
iOS CallKit provider and Android ConnectionService are wired to your signaling layer. We deliver working incoming/outgoing call flows on a reference device pair (latest iPhone + Pixel).
Media Pipeline Integration
RTCPeerConnection is configured with adaptive bitrate, simulcast, and the TURN/STUN infrastructure described on our parent WebRTC page. You get alpha builds with audio/video on both platforms.
Device-Lab Stress Testing
We test across 12–16 physical devices covering iOS 15–18 and Android 10–14, including Samsung One UI, Xiaomi MIUI, and stock Pixel. Tests include backgrounding, Doze mode, airplane-mode toggling, and 4G/Wi-Fi handoff. We also run network-degradation profiles: 5% packet loss, 300ms+ latency spikes, and captive-portal detection to verify ICE restart behavior under real-world cellular conditions. You receive a pass/fail matrix with remediation tickets.
Store Submission Prep
App Store and Play Store metadata, privacy labels, and background-audio justification strings are drafted. We handle the review dialogue if Apple or Google flag the VoIP entitlement. You get production-signed binaries ready for release.
Post-Launch Telemetry
We instrument WebRTC-internals metrics (jitter, packet loss, ICE candidate pair switches) into your existing analytics. You receive a Grafana dashboard and a 30-day burn-down of P0 connectivity bugs.
We don't just deliver software.
We build systems that scale, perform, and last.

Adaptive Simulcast for Cellular Uplink
Adaptive simulcast tuned for cellular uplink variance, so a user on 4G doesn't force desktop participants to degrade. The SFU receives multiple spatial layers and forwards only what the downstream link can sustain. For live and interactive streaming targets, see our production guide on reducing WebRTC latency.
VoIP Push Notifications (PushKit + FCM)
Incoming calls wake the app reliably even when it is suspended. iOS uses PushKit VoIP pushes (not standard APNs) to trigger CallKit immediately; Android uses high-priority FCM data messages to start the foreground service before the caller times out. This prevents the missed-call problem that kills retention in the first week.
Native Incoming Call UI
CallKit integration on iOS and TelecomManager/ConnectionService on Android, giving users native incoming-call screens with swipe-to-answer gestures, system-level call logs, and full-screen lock-screen integration. Users trust the system UI because they already know how to interact with it.
Background Audio & Foreground Services
Foreground service with partial wake-lock on Android and audio-background entitlement on iOS, keeping the microphone alive when the user switches to another app or locks the screen. Calls survive backgrounding without drops.
Battery-Optimization Whitelisting
Battery-optimization whitelisting flow and runtime permission coaching prevent Samsung One UI, Xiaomi MIUI, and other OEM skins from suspending your process after a few minutes of background activity. We handle the OEM-specific permission dialogs so users don't bounce at the first call.
Wi-Fi-to-Cellular Handoff
ICE restart logic bound to Reachability (iOS) and ConnectivityManager (Android) network-change events, enabling Wi-Fi-to-cellular handoff without user-visible drops. Media resumes on the new path in under 2 seconds when a TURN relay is already allocated.
End-to-End Encryption & Multi-Party
DTLS-SRTP with certificate pinning, plus SFU media server compatibility for multi-party calls. For security and compliance hardening including HIPAA/GDPR variants, we add audit logging and E2EE key rotation.
