2019. Anti-spam service Truecaller adds free voice calling feature


Truecaller, the app best known for helping users screen calls from strangers and spammers, is adding yet another feature to its service - free VoIP-powered voice calls. The company has started to roll out the free voice calling feature to its Android users. The feature, which currently only supports calls between two users, will arrive on its iOS app soon. The addition of voice calling functionality comes as Truecaller aggressively looks to expand its business. The service, which offers both ad-support free tier and subscription bundle, has added messaging, mobile payments, and call recording features in recent years. Earlier this year, it also added a crediting option, allowing users in India to borrow a few hundred dollars.


2014. Microsoft launches Skype for Web



Skype has brought its instant messaging, voice and video chat service to the browser with a new beta available now. For now it requires you to install a small plug-in to get voice and video calls, but Microsoft promises to bring Real-Time Communications (RTC) support, so you'll be able to use it without any plug-ins. Skype for Web works on Chrome for Windows, IE, Firefox or Safari. Chrome on Chromebooks and non-Windows platforms can use Skype for Web for instant messaging, but not yet for voice and video because the plugin hasn’t been configured for them yet. Skype had already come to the web in one form thanks to a plug-in for Outlook.com launched globally earlier this year, which enabled text, video and voice chat through the company’s web-based email inbox service.


2013. Viber now can call landline and mobile phones



Until now Microsoft wasn't touching Skype and most people continue to use it. But if MS take just one mistake step - there is a crowd of services that want to replace Skype as a defacto-standard of Internet communications. And the first in this crowd is Viber. This service gained considerable popularity (over 200 million users) thanks to mobile-first strategy and simple authorization via mobile number. And at the moment Viber and Skype are virtually identical in their features. Recently Viber eliminated, perhaps, the last gap - added the ability to call landline and mobile phones at cheap rates. Rates (as expected) - are slightly lower than Skype. For example, 2.5 cents to Indian landlines (4.5 cents to mobile phones), 2.3 cents to Mexico (9.9 cents to mobile), 2.3 cents to all China numbers and 1.9 cents to the U.K. (5.9 cents to mobile). This new feature works on Android, iPhone and Viber dektop (PC and Mac).


2008. Fring VOIP and chat client goes mainstream



The iPhone app Fring , which acts as a VOIP client for Skype and other internet phone networks, as well as a voice and chat interface into IM networks like AIM and Yahoo, is now available for free to everyone. Previously it only ran on Jailbroken iPhones, severely limiting its audience.On the iPhone, Fring can read both your IM and Skype buddy lists as well as the contacts in your phone's address book, and when you select a contact, you get the option of calling him or her by SIP call, Skype, or standard cellular. VOIP calls obviously don't count against your cellular minutes, but you do need to have a WiFi connection to make the calls. The biggest challenge for Fring users is that it can't notify you of incoming calls or chats, nor indicate your presence to buddies, when the app is not actively running in the foreground on your phone. Apple has yet to provide background notification capability to iPhone developers, although we keep hearing it will be in an upcoming release.
