Basic features include instant messaging, Voice Over IP and Video Conferencing inside the client software.
Jitsi vs Microsoft Lync in our news:

2015 - Atlassian acquires Jitsi video chat maker to power HipChat and to strike back at Microsoft Lync

Atlassian announced that it has acquired BlueJimp the founder of the open-source chat and video conferencing tool Jitsi. BlueJimp’s technology will replace the current video chat technology that powers Atlassian’s HipChat video features, both in Atlassian’s hosted and on-premise versions. Atlassian promises to continue to support and develop the open source version of Jitsi going forward. Jitsi’s WebRTC-compatible Videobridge product is likely what Atlassian was mostly interested in. It’s a scalable video router that makes it easier for developers to build video chat services with multiple participants. WebRTC, after all, should make it easier for Atlassian to scale its video services and should make it easier — and more cost-efficient — for the company to offer its on-premise version of HipChat.

2013 - Microsoft connected Lync and Skype

Almost 300 million people around the world use Skype. This is a very large customer base, that's why many companies add skype-address to their contacts in order to offer customers a convenient communication channel. But in large companies using Skype at the workplace - doesn't fit the corporate security policy. Therefore, the integration of Skype with Lync communication server can become a breakthrough for deploying Skype in large companies. And thus Microsoft can get a significant competitive advantage over Cisco, Avaya and other enterprise communication vendors. That's was the main reason why Microsoft acquired Skype for a lot of money.

So now Lync (or Lync Online in Office 365) users can add Skype contacts to their contact list, see their online status, chat and call them. The same actions are available for Skype users.

What is not implemented yet: video calling, conferencing, support for Skype mobile apps. Microsoft promised to add these features later.

2010 - Lync 2010 becomes social

Lync 2010

Oh, we didn't rename our products for so long time, thought people in Microsoft and decided to rename MS Office Communications Server to Lync. The new version Lync 2010 with a status "release candidate" is already available for free download and contains a large number of new features as compared to OCS. Most interesting are social features, that we used to see more in social networks rather than in VoIP-solutions. First, the activity feeds that you can subscribe to view contact's status changes. Like in the location-services, Lync can determine the actual contact location by the network point to which he is currently connected. People search allows you to find the right person in the company by name and by the area of expertise. Another interesting feature - context call that allows users to push the conversation subject before making a call, so the contact could better prepair to the conversation.

Lync 2010 Communicator

As for the new communication features, Lync 2010 supports videoconferencing streams with resolution of 720p HD as well as panoramic HD-video.


The "simultaneous call" feature allows users to redirect incoming calls to any internal number or several numbers or directly to voicemail. Voicemail in Lync 2010 will be transcribed to text in real time, so that users could read the contents of the incoming voice messages.

Lync 2010

Microsoft will also release web-client Lync Web App and a new mobile client Lync Mobile (it's not clear yet for what platforms).

Commercial version of Lync 2010 is scheduled for the end of this year.

2007 - IBM follows Microsoft with unified communications push

Following Microsoft's partnership with networking giant Cisco, the unified communications market is heating up even further with IBM's launch of a new range of collaboration products.

IBM has joined forces with Siemens to turn its Lotus Sametime software into a product family that will include new telephony integration software.

The move comes as Microsoft confirmed the October 16 launch of its much-hyped Office Communications Server 2007 for larger enterprises. It plans to sell unified communications to smaller businesses as an on-demand service.

Unified communications pull together voice, video and data communications and a multitude of applications to allow employees to communicate more easily with a range of endpoint devices.

IBM said the new Lotus Sametime product family will make it easier for companies to create a unified communications environment that delivers essential capabilities to users and simplifies back-end integration--without forcing software migration or rip-and-replace decisions.

The central new product in IBM's vision is the Lotus Sametime Unified Telephony software, which is heavily reliant on Siemens' OpenScape communications technology.

The choice of Siemens by IBM has raised many eyebrows because Siemens has, up to now, been a close unified communications partner to IBM's rival Microsoft.

IBM seems to be hedging its bets as to which network suppliers it comes to rely on, as Cisco is also a close partner in getting its Lotus Sametime collaboration offering into the enterprise market.

In addition, IBM is working with Nortel to get yet another unified communications platform into the marketplace by the end of the year. Microsoft has already chosen Nortel as its main hardware provider in supporting Office Communications Server 2007.

"IBM chose Siemens OpenScape technology because of its interoperability with multiple PBX systems and track record of innovation and vision in this field," said Bruce Morse, vice president for unified communication and collaboration at IBM. "Our companies share the goal of developing extensible unified communications solutions that are based on open standards and integrate seamlessly into business processes."

Current OpenScape customers include SAP, Accenture and PepsiCo.

2007 - Microsoft wants your office phone

On Monday, Microsoft and nine leading phone manufacturers--Asustek Computer, GN, LG-Nortel, NEC, Plantronics, Plycom, Samsung, Tatung, and Vitelix--announced the public beta program for Microsoft Office Communications Server 2007 and Microsoft Office Communicator 2007. The program was announced at WinHEC, Microsoft's Windows Hardware Engineering Conference in Los Angeles. The software giant has provided the manufacturers with design specifications for the new communications architecture. Several products are nearing the end of the Microsoft qualification cycle.

Communicator allows employees to designate, through Microsoft Office, how they'd like to be contacted, seamlessly linking office phones, cell phones, and online messenger services together so that calls roam wherever you are. The Microsoft design specs released at WinHEC make it easier for customers to choose one of these phones, knowing that the qualified phone will integrate wholly with Office Communicator.

2007 - Microsoft Office finds its voice

After months of anticipation, corporate customers will soon get their hands on a beta version of Microsoft's voice over IP software, an event that marks an important step in the evolution of corporate communications.

Microsoft is staging the long-awaited coming-out party for its IP telephony software with an announcement that the public beta release of Office Communications Server 2007, Microsoft's voice over IP and unified communications server, and Office Communicator 2007, Microsoft's unified communications client, will be available to testers later this month.

The announcement will be made by Jeff Raikes, president of Microsoft's Business Division, during a keynote address Wednesday morning at the VoiceCon trade show in Orlando, Fla.

The launch of the new software puts Microsoft head to head with other companies selling IP telephony and unified communications software to large companies. As the No. 1 supplier of desktop software to most businesses around the world, Microsoft will likely be a formidable competitor not only to the traditional telephony players, such as Avaya, but also to its longtime partner and more recent rival Cisco Systems.

"Microsoft, because it is Microsoft, will have a big impact on the market," said Zeus Kerravala, an analyst with the Yankee Group. "They will be able to use their influence with customers on the applications and desktop front as another way into the customer account."

But more than adding a new competitor to the mix, Microsoft's entry into the corporate telephony market also marks the next evolution in communications. Tying voice services into Microsoft Office applications turns telephony into another software feature rather than making it a separate and standalone product that requires its own hardware and team of technicians to purchase, install and manage it.

Kerravala said he sees communications being embedded in a slew of other applications from wikis to blogs to podcasts, not to mention the vast array of business applications.

"Once telephony stops being a separate product, there is a lot of room to integrate it with some Web 2.0 technologies," he said. "Microsoft hasn't addressed this just yet, but they seem to be headed there. You shouldn't have to switch applications to make a phone call or send a message."

Raikes said during a recent interview that he believes a software-based approach to IP telephony could revolutionize corporate communications by reducing costs and improving the efficiency of interactions.

"When you get voice and unified communications integrated into the productivity and line of business application infrastructure," he said, "you suddenly open up all kinds of great new value that users really haven't been able to take advantage of."

Microsoft first announced that it was integrating telephony with its Live Communications Server last summer. Soon after that, it announced that it was working with veteran telecommunications equipment maker Nortel Networks to help provide corporate customers with a complete solution that included infrastructure equipment and call-signaling software, as well as desktop software to integrate communications into business applications used on a daily basis.

2006 - Microsoft's corporate IM goes mobile

Microsoft announced Tuesday at the 3GSM World Congress in Barcelona that its corporate instant messaging product will soon be extended to mobile devices.

The new product, called Microsoft Office Communicator Mobile, runs on the Microsoft Office Live Communications Server 2005. The new mobile client is integrated with the desktop version of the software, allowing workers on the go to communicate via IM even when they are away from their desks.

Not only does the mobile product provide secure instant messaging, it also offers integrated voice over Internet Protocol services and "presence" features that let other people see whether or not someone is online, on the phone or out of the office.

"The new client is a key component of Microsoft's vision for unified communications, putting people at the center and enabling information workers to have access to real-time communications capabilities virtually anytime, anywhere, on any device," Gurdeep Pall, corporate vice president for the Unified Communications Group at Microsoft, said in a statement released during the second full day of 3GSM activities.

Communicator Mobile is expected to be available for download for Live Communication Server customers within 60 days.

Last year, Microsoft announced that workers would also be able to access their corporate instant messaging via the Web through Office Communicator Web Access. The new tool lets employees get corporate IM from non-Windows devices. It also lets them receive messages from machines that are locked down and that don't allow new software to be installed.

2005 - Microsoft, Siemens push to collaborate

Microsoft and Siemens Communications Group announced a partnership Tuesday to market and sell a suite of software tools for enhanced corporate Web conferencing and communication.

Under the multiyear agreement, Siemens will integrate its HiPath OpenScape Telephony Control Link with Microsoft's Office Live Communications Server 2005 and "Istanbul" instant messaging client.

The integration will allow Microsoft Office users to click their mouse to make a phone call through a PBX or Internet-PBX connected phone sold by Siemens or other phone vendors. The technologies are designed to work with a typical desk phone, alerting users when a call comes in, then routing the call to a recipient's cell phone or voice mailbox. The Istanbul client synchronizes with Outlook's calendar and scheduling information to provide further information on finding the recipient.

The OpenScape telephony control link and Istanbul client will be available in the first half of this year and will be added to existing product lines. Pricing has not yet been released.

Sales representatives from both companies will meet with customers jointly but will represent their own products respectively, said Adam Moise, a Siemens Communications business development manager. He noted that the companies have not entered into a reseller agreement.

The partnership will further bolster efforts by Microsoft and Siemens to enhance the ways workers communicate with each other.

Microsoft's Live Communications Server 2005 and Istanbul will work with the software giant's Web conferencing service, Office Live Meeting. Combined, the technologies will be able to integrate telephony, video, instant messaging and Web conferencing into a suite of software tools. Siemens' HiPath OpenScape, meanwhile, is a collaboration portal that allows workers using a variety of devices from work phones to cell phones to locate one another and communicate.

The package of tools is part of a push toward "presence," in which people's computers help others make smarter choices about how to reach them. Instead of filling up voice mail, for example, correspondents will see that someone is in a noncritical meeting and shoot him or her a discreet IM. Presence is moving closer to implementation, although it's still likely to be several years before it's widely used.

"Our customers tell us they need to find and communicate with people in real time, and they need to successfully work together without having to be in the same place," Anoop Gupta, vice president of Microsoft Real-Time Collaboration, said in a statement. "Microsoft and Siemens are dedicated to delivering to our customers the industry's most enhanced presence and collaboration solutions."
