Our In-App Voice Calling utilizes WebRTC, the industry-standard framework for IP-based communication. This technology combines multiple protocols to deliver optimal call quality.
We primarily utilize OPUS, an adaptive audio codec that optimizes voice quality based on network conditions, delivering HD audio when possible. For video, we primarily employ VP8 codec.
Our platform flexibly supports applications of all sizes, from early-stage prototypes to large-scale deployments. We provide automatic scaling and ensure continuous availability.
Bandwidth usage varies by call type - whether voice-only, video, or phone calls. Reach out to us for detailed bandwidth specifications and guidelines.
We prioritize P2P connections using ICE protocol for NAT traversal. When P2P isn't possible (e.g., with symmetric NATs), we route through our media proxies. Typically, 70-75% of calls use P2P, while 25-30% utilize our servers due to network restrictions.
