Skype vs Tango


41
Skype
Skype is a software application that allows users to make voice and video calls and chats over the Internet. Calls to other users within the Skype service are free, while calls to both traditional landline telephones and mobile phones can be made for a fee using a debit-based user account system. Skype has also become popular for its additional features which include instant messaging, file transfer, and videoconferencing. Skype alternative for enterprise is called Skype for Business. Secure Skype alternatives are Signal and Telegram.

Tango
Tango is a free mobile video communications service that allows you to connect with friends and family to conveniently capture and share life’s every day moments. Tango works on the iPhone, iPod touch, iPad, and all Android 2.1 or later phones and tablets over 3G, 4G, and Wi-Fi, giving you the ultimate flexibility in how, where and with whom you communicate.
Skype has better video than Tango

Face to face in the news:


2016 - Skype discontinues its video messaging app Qik to catch up with Tango


Skype Qik, Microsoft’s attempt at spinning off video messaging into a simplified mobile application, is shutting down. The app was first introduced in fall 2014 to serve a different audience than the larger, more fully-featured, Skype application. Instead of offering real-time chat, screen sharing and audio and video calling, Qik was designed only for asynchronous video messaging. The app shared its name with the mobile video startup Skype acquired back in 2011, but the technologies were completely different. The older version of Qik was about live streaming. With new Qik, users could communicate by quickly sending video messages.  However, according to a post on the Skype Developers’ blog, many of the ideas from Qik have now made their way over to Skype’s main application – including video messaging. Because Skype now supports Qik’s core functionality, the Qik app is being shut down.

2012 - Skype finally comes to Windows Phone to fight Tango



Nine months (!) after Microsoft announced the acquisition of Skype, this messenger finally comes to Windows Phone (in beta version so far). Interestingly, already after the deal with Microsoft, Skype appeared on the competing platform Android and before that it worked on the iPhone. The things got so bad that in November 2011 Microsoft began to preinstall the alternative video chat app Tango on Windows Phones. But now this circus is over - Skype for Windows Phone is already available for free download from the marketplace. However, it doesn't work in the background, so for now you have to launch it every time to make a call or send a message (or launch it to receive a call). Also  the beta version doesn't allow to add/edit contacts. And if the absence of Skype was the only thing that stopped you from buying Windows Phone, do not forget about the main thing - check that the Windows Phone has a front camera when you buy it.

2011 - Tango launches Windows-apps, gets 42 million to replace Skype

Tango for Windows
After Microsoft's Skype acquisition we started looking for its replacement as of public communication service. And, apparently, not only we, but also the investors who want to raise money on this project. From now one of the main contenders for the Skype's place - is Tango. It has just closed $42 million in its Series B round of funding led by Draper Fisher Jurvetson, notably the first outside investors in Skype. Tango launched 18 months ago and already has 18 million users. Every 2 weeks it adds a million. Until now, Tango was a mobile service. It allowed to make video calls on iPhone, iPad and Android (smartphones and tablets). But now it introduced the Windows app, and soon plans to create the Mac-client. So how is Tango different from Skype?

For end users, what makes the service different from Skype is a minimalist feature set. Tango doesn't allow to make calls to regular phones, doesn't even includes text chat. It can do only one thing - video chat. And it doesn't require registration. You simply enter your phone number. After that, Tango scans your phone address book, determines which of your contacts have Tango installed and adds them to the contact list. And then you can make video calls to them. A similar process will be offered in the PC version, too.

2009 - Skype+Asterisk are now ready for business to win over Tango

Skype Asterisk
Skype and Digium (Asterisk developers) announced the official release of the Skype for Asterisk connector. This solutions allows to integrate Asterisk IP PBX or Asterisk based telephony systems with Skype network:
- make calls to Skype-users from the common office phones or ip-phones
- make calls from office phones to PSTN and mobile lines all over the world at SkypeOut rates
- receive Skype-calls to single corporate Skype account (or SkypeIn number) and redirect them to office phones
- in the same way receive calls from your site (with the help of CallMe button)
- set IVR menu to your corporate Skype account
- log incoming and outgoing Skype-calls
- manage Skype services, like voice-mail and conferencing right in the Asterisk

You can order the connector for the one-time license price $66 per Skype-line. As opposed to the new rival Jajah+MS Communications Server, Skype+Asterisk is more attractive solution for small businesses, especially for these that make a lot of long-distance calls.
