## Usage

First of all you have to initialize module to be able to work with it.

There are some interesting moment in initialization. When application goes to background, PJSIP module is still working and able to receive calls, but your javascipt is totally suspended. When User open your application, javascript start to work and now your js application need to know what status have your account or may be you have pending incoming call.

So thats why first step should call start method for pjsip module.

    import {Endpoint} from 'react-native-pjsip'

    let endpoint = new Endpoint();
    let state = await endpoint.start(); // List of available accounts and calls when RN context is started, could not be empty because Background service is working on Android
    let {accounts, calls, settings, connectivity} = state;

    // Subscribe to endpoint events
    endpoint.on("registration_changed", (account) => {});
    endpoint.on("connectivity_changed", (online) => {});
    endpoint.on("call_received", (call) => {});
    endpoint.on("call_changed", (call) => {});
    endpoint.on("call_terminated", (call) => {});
    endpoint.on("call_screen_locked", (call) => {}); // Android only

Account creating is pretty strainghforward.

    let configuration = {
      "name": "John",
      "username": "sip_username",
      "domain": "pbx.carusto.com",
      "password": "****",
      "proxy": null,
      "transport": null, // Default TCP
      "regServer": null, // Default wildcard
      "regTimeout": null // Default 3600
      "regHeaders": {
        "X-Custom-Header": "Value"
      },
      "regContactParams": ";unique-device-token-id=XXXXXXXXX"
    };
    endpoint.createAccount().then((account) => {
      console.log("Account created", account);
    });

To be able to make a call first of all you should createAccount, and pass account instance into Endpoint.makeCall function. This function will return a promise that will be resolved when PjSIP initializes the call.

    let options = {
      headers: {
        "P-Assserted-Identity": "Header example",
        "X-UA": "React native"
      }
    }

    let call = await endpoint.makeCall(account, destination, options);
    call.getId() // Use this id to detect changes and make actions

    endpoint.addListener("call_changed", (newCall) => {
      if (call.getId() === newCall.getId()) {
         // Our call changed, do smth.
      }
    }
    endpoint.addListener("call_terminated", (newCall) => {
      if (call.getId() === newCall.getId()) {
         // Our call terminated
      }
    }

## API

1. Startup
2. Accounts
3. Calls
4. Settings

## Demo

The demo project is https://github.com/datso/react-native-pjsip-app. And you will need a SIP server.
