Please execute below as root user.
  1. Please disable selinux to avoid strange behavior during installation
    1. Run ‘sestatus’ to check selinux state
      1. if enabled, please run below commands
        1. sed -i 's/\(^SELINUX=\).*/\SELINUX=disabled/' /etc/sysconfig/selinux
        2. sed -i 's/\(^SELINUX=\).*/\SELINUX=disabled/' /etc/selinux/config
        3. Reboot
      2. If disabled, run step 2

Implementing Client Side WebRTC using Sipml5 javascript

Step 1:

Download and require Sipml5 library function.

Step 2:

Initialize sipml5 Engine in your web page :

var readyCallback = function(e) {
// function called when sipml is successfully initialised.
createSipStack(); // calling this function to create sip stack(see below)

var errorCallback = function(e) {
// function called when error occured during sipml initialisation.

SIPml.init(readyCallback, errorCallback);

Step 3:

Create Sip Stack :-
Sip Stack is an object that must be created before making/receiving call and sms. Creating Sip stack is an asynchronous process, so you need to create an event listener function to get state change notification.

var sipStack;

function EventListener(e) {

* e.type ;type of event listener
* e.session ; current event session
* e.getSipResponseCode() ; event response code
* e.description ; event description

if(e.type == 'started'){
// successfully started the stack.
} else if(e.type == 'i_new_call'){
// when new incoming call comes.

Start an android activity from cordova plugin

We all need to start an android activity from a cordova plugin. Here is a small and complete code to start an activity from cordova plugin
1. Install plugman to create cordova plugin npm install -g plugman2. Create cordova plugin using plugman plugman create --name PluginName --plugin_id com.example.sample.plugin --plugin_version 0.0.1
N.B : plugin id never start with Uppercase Now PluginName directory will be created. Plugin structure will be
> PluginName/

> |- plugin.xml

> |- src/

> |- www/PluginName.js

3. Add android platform to plugin
plugman platform add --platform_name android
Now plugin structure will be

> PluginName/

> |- plugin.xml

> |- src/android/

> |- www/PluginName.js

4. Now create a java file named in src/android diretory
This activity will be shown using our plugin. Write sample activity in
package com.example.sample.plugin; import; import android.os.Bundle;…
