SoftPhones – first steps and installation

SoftPhones

Definition:

The technical term ‘Softphone’ is used for software applications which run on any device (mobile, laptop or desktop), and has telephone like functionality. Soft Phones are used to place VOIP calls which are generally cheaper when making international calls. Most of those applications actually run on hard phones(phones made specially for VOIP purposes) but there are planty also made for mobile and pc. The softphones work similar to any actual phone, with functionalities  like outgoing & incoming voice calls and outgoing/incoming Video calls. They are basically IP based phones, providing VoIP ( voice over IP) functionality, governing protocols such as SIP( session initiation protocol) , or H.323 or SCCP or any other similar proprietary protocol.

Examples of softphones for desktop and mobile:   X-lite, zoiper, Pindo, vChat, Whatsapp , Skype.

Procedure & Functionality :

There is quite a big diversity in soft phones . Some are made to serve the masses, and they are mostly free, while others are business and enterprise oriented with license versions. Softphones can be classified as a type of IP-phone with no hardware. The software supplication of the softphone available based on the OS platform basis Linux, WINDOWs, MAC like X-lite, etc. Following are the procedure steps for setting up the softphone:

  1. Software Installation
  2. License key configuration, if any
  3. Configuration

Procedure

  • After successful installation, License key is entered to within the application of the software to make it working.
  • Few trial version of the softphone are available with limited edition i.e., once softphone installation is installed and running, it bind itself with the PC/Desktop/Laptop MAC address and this information is send to centralised server of the software.
  • This is done to avoid multiple installation of softphone on same machine.
  • Once the tenure of license expire, softphone stops working until license is renewed again.
  • Post License key configuration, desired network and dial plan related configuration is done in order to get it registered with server, which is VoIP server.
  • The IP –address of the system (PC/Desktop/Laptop) is used as the IP-address of the softphone itself.

Functionality

  • Initial configuration of the softphone after installation also involves providing the IP-address of the proxy server which will be anchoring all services of the softphone like registration and call.
  • Softphone does its registration with the VoIP network in which Softphone Address-of-record (AOR) is populated in the VoIP location server database, and now softphone ready to send or received any call.
  • Most common usage of such softphone to test the network functionality.
  • Another usage of such softphone to perform load and stress testing of the network.

On Mobile

In Public network for mobile user: softphone is generally available as a mobile application. The software applications  are uploaded to public server like PlayStore or AppStore, from where the user can download it on his mobile. Most such apps require the user to have stable internet connection to operate (with the exception of Pindo and Rebtel). In the mobile market softphones are dominated by free apps  and there is almost no paid versions.. Following are the procedure steps for setting up the softphone on mobile:

  1. Software Installation
  2. User Profile creation

Procedure

  • Softphone application is downloaded from play-store in a single click and get installed automatically on the supported version of the Mobile OS/Platform.
  • After successful installation, softphone application is brought up on the mobile by a click and user profile is created. Since such softphone is available for public use, hence the user profile creation steps generally involves linking with public social network, like twitter, Facebook, LinkedIn etc, and name/password, and OTP verification to authenticate user mobile number
  • Upon successful completion of the user profile, installed softphone is available to function as per designed functionality/feature.

Functionality

  • Most such softphones doesn’t require any pre-configuration of network details.
  • The Server/Network details is in build within the software downloaded and ready to use more readily

Future:

If I have to make a bet I would bet on softphones with html based user interface. They are mostly used for commercial purpose like Video-Conferencing, license based conferencing for entrepreneurs, meeting, three-way calling etc. They come with Pay-and-Use functionality, and most of them are based on SIP protocol for session creation and media streaming.

Open Source at a Glance

How to Get Started with Open Source?

Gentle warning

OSS projects aren’t completely related to standards and prototypes. If a present project is adopted, the approach goes straight to the Execution phase. So if a given project is under a really short permissive license, and a group of organizations can choose to supply an extra layer over the project . It is difficult to run an open-source project following a more conventional software development method like the waterfall model. In these standard methods it isn’t permitted to return to a former phase. So be certain you define the undertaking and that you communicate that definition clearly to the remaining portion of the team.

Few rules

  • Open source projects aren’t all community-based.
  • All open source projects have to be hosted on a site that’s accessible to the general public.

Together, an international community can create past the capabilities of any 1 individual. Then again, there are numerous added benefits of open source program. You ought to take advantage of this tool for the very simple reason it makes everything so much simpler for you. In such cases there is not any implicit advantage in using the web. At the exact same time, the usage of open-source software is expanding rapidly, and even commercial software companies often offer open-source licensing choices and opportunities. You can always choose is to develop an in-house solution in which you acquire or employ a group of professionals for the evolution of a customized solution based on your wants and wishes.

The success of Wikipedia and other digital content providers employing open source methodology demonstrates that the open source model proceeds to evolve. And it will probably continue to be a significant part of the digital economy. As a consequence of its open source license WordPress has come to be the dynamic web publishing platform it is today.

Choosing Good Open Source

As a good example, Ramadan 2015 Android App give you all of the 99 allah names at one spot. Any application should have a specific uniqueness which will capture the interest of the users. The application build needs to have some essential features, in other words, it has to be reliable, customizable and serviceable. It should target a maximum number of users so that the business brand will get recognition. For that, a proper advertising is required, so that a growing number of folks are enticed to use the application.

Open source software is normally free, and so is a huge support during the vibrant communities surrounding each bit of software. Open source software may be cost-effective approach to run many forms of programs on your PC. Open source software, on the flip side, is typically not as resource-intensive, meaning that you may run it well even on older hardware.

The development of the web is making a bigger spectrum of projects out there. Open-source program development can be split into several phases. It’s therefore essential to encourage the developers to work together in the development procedure to make sure the organizational goals are satisfied. It’s possible to also hire open source developers from ANGLER at reasonable price. Developers can get the job done directly with Findbugs. Most OSS developers have experienced the should fulfil a specific requirement.

Top open source alternatives to Slack team chat

There are a lot of open source alternatives when it comes to team chat software.

As it is with every team collaborative environment, communication is very important. What software works best in your case depends on your requirements and preferences.
The first collaboration tool that comes in mind is the indispensable team chat. It does not matter if your work colleagues are sitting across the room from you or on the other side of the planet. Communication in real-time makes conversations faster, easier, reducing confusion and misunderstandings.
While some circles still think that chat applications van be distraction. And they sure can be one if not contained. But I believe that if you are committed to your work, you can come to agreement to reel of-topic chats. Creating “general” channels can help loosen up, leading to better work flow. But it is equally important to be able to give yourself the space to work uninterrupted. While writing this article I have three team collaboration tools running in background. Still I keep all my notifications silenced and I check them only when the breaks in my work allow for it.
 
I recommend using an open source tool that is made exclusively for work. I like to separate work from personal communications and that is the main reason for me to try the software listed bellow.
 

Slack

Slack is the corner stone when it comes to collaborative chat software. It is preferred by the software development companies and for a good reason. It is stable, well designed and with all the right options. But Slack is not open source not to mention that it is pay to use. As such it is not very flexible. As a simple example is that you cant self host it. For big companies with lots of sensitive data this is a major turn off.
 
Open source with its access to the code helps you ensure that all communications stay private. Of course I should mention the option to add or remove features to further improve your work flow.
 
Let’s check five open source Slack alternatives. From the classics to brand new applications, for your team’s communication needs.

IRC

An honorable mention. The truth is that it has no place in any modern company. IRC has been around for a while – about 30 years actually, and it has tons of open source implementations.
As always with the age, come the drawbacks. It lacks features that are must for every modern chat. Security and Identity management barely exist (they are implemented with bot services).
 
On the good side, IRC is universal. Both servers and clients are available for every platform you can think of. The interface while not something to brag about is intuitive and fast. And if you have been developing open source, you most probably already installed or used IRC.
 

Let’s Chat

Let’s Chat has a more modern approach to team chat. Its program (also called Let’s Chat) is with MIT license and written on top of the popular Node.js platform. You will find many of the things that are expected of chat client like Slack. Image embeds @mentions, logging and file management. With Let’s Chat you can create chat rooms for every team, or project. It can integrate with your existing authentication servers. This way you can use the same login across all your software in your organization. As an addition Let’s Chat has a nice API that allows it to connect with other tools too.
The program is easy to install and self hosting is not a problem too. You can do it by Vagrant or Docker, or as part of Sandstorm.io. There is an online demo, that does not implement all the features of the project. You can still get the general Idea of the program.
 
 
 

Mattermost

Mattermost is another app with modern approach. It is advertised as private cloud Slack alternative. It is written in Golang with a bunch of JavaScript under the hood of React framework. It supports both public and private chats as well as one on one conversations. It saves archives and is very similar to Slack interface wise. You can find all the expected team chat features. For people switching from Slack there is an import function that will import channels and chat archives.
Sadly as of late only the Team Edition is open source and free.
 
 

Rocket.Chat

Rocket chat is my personal favorite. While it can be buggy at times if you are not using the Rocket chat+ client it is a descent program.
Rocket.Chat is written in CoffeeScript and JavaScript on top of Meteor framework. It is available under MIT license. Like most others it is with descent interface and available for both desktop and mobile. It is feature rich with the only thing that I am missing is the “talk to self” option.
Installation is easy and everything is well documented. The server can be on-premise or cloud based on their servers (paid option). As with most programs now days its available on every viable platform. There is an online demo that you can check.
Rocket.Chat features an online demo, and you can check out its source code on GitHub as well. Rocket.Chat is available under an MIT license.
 
 

Riot.im

Riot.im was one of the less popular chats but things have changed fast. It rightfully sits among the top alternatives of Slack now. Riot has quite a bit of mobile and web tools that connect to Matrix network. Matrix is open network for secure and decentralized communication. Among the functions I should mention its VOIP implementation. Bridge integrations with Slack, Gitter and IRC are available, for easy replacement with the open source client.
 
It is the easiest tool to try since it is web based (both client and host). Riot is licensed under Apache 2.0 license.

Other options

This is my personal favorites list and it is far from exhaustive. I encourage you to try and find a few others before you decide what chat to use.
Don’t take everything written in this list for granted. Lately more and more open source software companies are turning the back on free software. Some time has passed since I used some of the tools above and can I give no guarantee that they are still free or open source.

Team Talk 5 review

TeamTalk is VOIP conferencing system that people use to communicate using VoIP and/or video streaming. The part with video streaming puzzles me as the program has community made of mostly blind people. They can log in with a simple tt document and converse easily with their contacts. The project is open source and using open source solutions for most of its functionality.

Functionality

  • Audio and video transfer with VOIP
  • Public and private channel creation
  • Sharing of desktop aplications
  • File sharing
  • Standalone server

Installation

The TeamTalk 5 conferencing system is composed of a client and hosted server. Most users will just need to install the client application, unless of coarse they want to have their own TeamTalk 5 server.
When installing the application on Windows, the visually impaired users, should install “TeamTalk 5 Classic. It is the client with better accessibility, since the Classic version works smoother with screen readers. There is also a regular TeamTalk 5 client developed for the masses.

Open Source

TeamTalk is a freeware. The program can be found on a lot of popular software websites. Its license permits, to be run on numerous clients or servers, it can be also redistributed free of charge. A permit must be nevertheless bought by developers that want to implement or use the code in third party programs.

TeamTalk client software have been build around the GitHub project TeamTalk5. The TeamTalk server is not part of the project and is therefore not publicly available.

Availability

The TeamTalk 5 can be downloaded for Windows, Mac OS X, and the most used Linux distributions – Debian, CentOS, and Raspbian. The server and client applications run on the same platforms. The only difference being that the client additionally supports the mobile platforms of iOS and Android.
