How to Integrate In app Voice Call APIs into Existing Apps

For every browser and mobile application there is a need for an open source setup for which WebRTC is the solution that is available with real-time communication (RTC) capabilities via simple APIs. WebRTC owns a real-time, media, peer-to-peer exchange between two devices.

However, the entire connection gets inaugurated via a discovery and negotiation process known as signaling. The WebRTC initiative is an extremely exciting industry that allows “real-time communication” via voice, video, and chat between the browsers without java or flash browser plugins.

What is Signaling Server and Peer-to-peer Connection?

When it is about coordinating communication the process is known as Signaling. In terms of WebRTC applications to set up calls, there is a need for the clients to exchange the information so as to proceed further. Moreover, signal is something that is used to exchange three types of information,

  • Session control messages
  • Network configuration
  • Media capabilities

Mostly, before beginning with peer-to-peer streaming, the exchange of information via signaling must be completed successfully. Once this process is done the data can be streamed directly between the caller and callee via an intermediary relay server (TURN Server).

WebRTC Peer to Peer connection

As the communication via streaming is the job of RTCPeerConnection, all its components handle stable and efficient communication of streaming data between peers. However, ICE is a framework that is specifically for connecting peers, as two video chat clients etc. Initially, in the beginning ICE tries to connect peers directly, with the lowest possible latency rate via UDP.

Real time WebRTC Peer connection

It is the process where STUN servers have a single task that can enable a peer behind a NAT that is to find out its public address and port.

When it comes to the tasks the WebRTC applications needs to perform several things,

  • Fetch streaming video, audios, and other data
  • Fetch network information and exchange them with other WebRTC clients that are known as peers. This is to enable connection through NAT and firewalls
  • To report errors and start to close any session
  • Exchange of information about media and client capabilities
  • Interact with streaming audio, video, or data
