Hello everyone,

unfortunatelly, I’ve missed the Lync conference in Las Vegas this February (, but after watching very exciting keynote, I’ve decided to make some post of it.

Microsoft has really gotten into the communication business, and this is really cool. Not only its market share has increased largely (and meanwhile it beats some of the greates competitors), it also finally goes online. I don’t mean that it hasn’t been there with Lync mobile and Lync web conference, but this time, it smashes with UCWA and now-annonced UCJA – which, I think, will spin the wheel around Lync greatly.


As you probably already know, Unified Communications Web API (UCWA) has been around for some time, but just for demo purposes, providing only the basic functionality for web development for Lync Client ( It is designed to provide a REST-like API for Lync Server 2013 for accessing middleware functionality (namely, UCMA), which was ‘unjustly’ hidden from the Lync client developers. UCMA is great platform, and if you needed to make some real good Lync integration with the current communication system, you had to use it. Now, UCWA is exposing in some extent this API and you can code against it – if you are fine with presence publishing, IM and some basic object model parts as contacts, and so. But, IMHO, it’s really a PoC which served creators of UCWA to test some web-related topics, as OAuth, or REST. You can’t do an audio or video call with it, so no usage for voice (telephony) integration.


On the other hand, Google (with Mozilla and Opera) has been doing a vast research lately to offer a real-time communicaton in a browser, by using just a JavaScript and HTML5 code ( There are some demos and documentation about what is already done, but I think, there would be some (maybe long) time until it becomes a W3C standard and everyone start to use it. In order to make this happen, it shall provide some low-level API and support, since it mandates that requires no additional plugins, downloads and updates. We’ll see about that when it’s finally ready.

Unified Communications JavaScript API (UCJA, jLync)

Well, this sounds very promising! Imagine that: a JavaScript API for Lync Client that will make it possible to integrate your web application (for instance, made with some SPA framework, like Durandal or Angular) with the Lync client fully in the browser! This is actually presented on the Lync conference keynote, and it would mean that, as a JavaScript developer, with “just several lines of code”, you will get a new object model that would sit on top of UCWA and make adding voice/video to your web applications. Stunning!

The only thing that I’m missing here is: when it will be available? Albert Koiman said “it will be here when it is here”, Gurdeep “by end of year”, and some rumors say “in the first quarter of 2015”. Well guys, I just can’t wait so long!

Kind regards,
