Accept incoming audio call using React Native

[josemaria...@11811.es]

Hi everybody.

I'm trying to run incoming audio calls using SIP.js + react-native-webrtc, but at the moment is impossible for me. I will be infinitely graceful for some help. My dev environment versions are as follows:

• SIP.js 0.20.0
• react-native-webrtc 1.98.0
• react-native 0.67.3
• react 16.11.0
• Testing in Android 7.0

At the moment, the issue is in "session is entablishing":

Here is the whole INVITE transaction: https://gist.github.com/josemaria11811/e81f4e34b10a926ec65f01d955851c01

I'm aware of I need to create my own SDH, but I have tryed with many code splits from the Google Group and I've never reached to pass to "Session has been established". These splits are as follows:

• At the UA configuration, add SDH Factory:
  sessionDescriptionHandlerFactory: (session, option) => {

            const se = SessionDescriptionHandler.defaultFactory(session, option);

            return se;

        }, Now, my userAgent create without SDHFactory returns me this: https://gist.github.com/josemaria11811/89bdfb3d734dcb291ca3276d704cad1f
  I have read that it can use for SDH in SIP.js 0.16, but I dont know if in 0.20.0 version it is still necessary.
• In the accept(options):
  const options: InvitationAcceptOptions = {

          sessionDescriptionHandlerOptions: {

              constraints: {

            audio: true,

            video: false,

          }

            },

      }

I know the issue possibily is coming from a concept error using SIP.js + react-native-webrtc. But beleive me, I have spend almost a week fighting against this and trying to understand the SDH configuration in not web environment.

Thanks a lot in advance.

Finally, I solved the issue.

You has to follow this thread to the letter. It's very important to set sessionDescriptionHandlerFactory: (session, option) into UA configuration with the version 0.16.1 SessionDescriptionHandler. You can use several SIP.js versions aplying alias in yarn or npm install / add.

You have to import this library for SDH:

import {SessionDescriptionHandler} from 'sip.js16/lib/platform/react/';

In the UA configuration, you have to set this:

sessionDescriptionHandlerFactory: (session, option) => {

        const se = SessionDescriptionHandler.defaultFactory(session, option);

        return se;

      },

For the invite, you have to handle the audio using the react-native-webrtc library:

const onAcceptCall = () => {  

        const options: InvitationAcceptOptions = {

          sessionDescriptionHandlerOptions: {

            constraints: navigator.mediaDevices.getUserMedia({ audio: true, video: false})

          },

        }

             

        incomingSession.accept(options).then(() => {

          console.log("Successfully sent INVITE");

        })

        .catch((error: Error) => {

          console.log("Failed to send INVITE" + error);

        });

      };

When session is in established state, you must to start the audio using InCallManager:

case SessionState.Established:

                console.log("Session has been established.");

                InCallManager.start({media: 'audio'});

              break;

Can you share your code for incoming call in react native

I've added like this and imported below line

import {SessionDescriptionHandler} from 'sip.js16/lib/platform/react/';

Getting. this errro 

[Error: undefined Unable to resolve module events from /Users/shraddha/Documents/Rectnative_projects/FONIMO/Third/node_modules/sip.js16.js/lib/platform/react/session-description-handler.js: events could not be found within the project or in these directories:
