Running UCMA 2.0 applications on Lync Server 2010
While the most ideal scenario is to only run UCMA 3.0 applications with Lync Server 2010, for many of you this is simply not possible. You may own an application that was written for UCMA 2.0 and you want to upgrade to Lync Server 2010, but the application has not yet been updated to UCMA 3.0. Likewise...

The Complexity of Simple Urls
One of the many new features in Lync Server 2010 is a change to how meeting Urls are formatted. The name of this feature is "Simple Url", but in truth this this elicits a smirk from anyone on our team who has dealt with them, as simple Urls are anything but simple. The goal of this blog will be to shed...

We have a new name!
For those of you who haven't seen a blog from me in over a year, you may be happy to hear the following information. I am alive and well, with this post serving as evidence of the former. We have a new name for our product - Microsoft Lync Server 2010. Those who have followed our product...

UCMA 2.0 - Part 1.6 Introduction to SDP
We are almost at the point where our Powershell commandlet will be useful, but first we need to learn about establishing the session protocol. You see, SIP stands for “Session Initiation Protocol”. The key here is the word “Initiation”. Yup, SIP just manages telling so and so that so and so wants to...

UCMA 2.0 - Part 1.5 Setting up a session
In our next iteration, we will add to our commandlet to create a signaling session. In essence we will send an INVITE to the other party so that we can send a message later. There are a number of steps involved in setting up a session but for now we will just send the INVITE. When running this sample...

UCMA 2.0 - Part 1.4 Signing in and signing out
It’s about time that we began writing some code and getting into the details of the API. To start out, I will cover the signaling part of UCMA. Those of you who read my previous blog series on UCMA will find the next several posts very familiar. For some of you, learning the signaling APIs in UCMA...

UCMA 2.0 - Part 1.3 Powershell and UCMA
Today, we will get started with coding UCMA applications. First though, I would like to cover again the Signaling namespace exposed by UCMA. While much of this is not necessary when using the new Collaboration namespace, I feel that it is still important in terms of understanding how the API and SIP...

UCMA 2.0 - Part 1.2 - Asynchronous pattern and threading model
Before you really start coding in UCMA 2.0, or even UCMA 1.0, it is extremely important that you understand the asynchronous pattern. UCMA is designed for server applications, meaning it supports many operations occurring at the same time. In order to best manage this, it uses an asynchronous model....

UCMA 2.0 - Part 1.1 - High level architecture and design of UCMA
Let’s be honest, UCMA 1.0, while very useful, was a bit lame. The frustrating thing about it was it opened up many new possibilities, but didn’t give you the chance to take advantage of them. You could send messages to another party, but could not determine that user’s presence. You also were very limited...

The "new" blog
In truth, this is now a new blog. I'm not sure what we will be covering in the next several months, short of the already stated UCMA 2.0 APIs. However, there are some sharp differences between this blog and my old one. First, it already has a new look and feel. I would love to personalize the site...

Ready for some new UCMA blogs?
At long last this blog is back up and running. Very soon (current goal is Wednesday), I will start a new series of UCMA blogs covering the new 2.0 API. My goal is to eventually cover all parts of this now huge set of APIs, but unlike my previous set of posts on UCMA there will be some changes. ...

Office Communications Server Resource Kit ships
OK, this may be old news to many of you out there, but the Office Communications Server 2007 Resource Kit just shipped. I haven't had a chance to look at it yet but you can be sure I will. I hope to receive a free copy of it at an internal event next month, at which time I also hope to sign up to contribute...

How to track down the WMI error in OCS
There are some product architectures created here at Microsoft that I am marvelled at with their simplicity, ease of use, and power. Unfortunately, I do not find WMI to be one of those architectures. With hope, some day we will have a sane replacement for WMI but in the meantime we still need to deal...

Doing good things while working at MS
Working at Microsoft is really interesting in that I often see my work being used throughout the world. It was nice seeing the press about the Unified Communications launch, knowing that I helped participate. Executives here like to mention that we are changing the world and affecting people's daily...

Where OCS finds data for WMI classes
In yesterday's post, I discussed how knowledge of where the WMI provider retrieves its data is important when querying it. Today I thought I would provide a list of the WMI classes and where the data comes from for each. If you perform a lot of WMI querying in OCS, this list may be helpful. Note that...

Office Communications Server and WMI
As many of you are likely aware, Office Communications Server (and previous versions) make use of WMI for storing various pieces of data. You can find details of the WMI classes that currently ship with OCS 2007 here . While this gives helpful information about what types of classes and properties are...

Thoughts on testing speech applications
Personally, I feel one area that we did not address overly well in Speech Server is allowing developers to test their speech applications. Granted, this seems to be missing from many platforms these days but I think in the case of speech applications this is especially important because they can be tricky...

Unified Communications Client API shipped!
I just received an e-mail that the Unified Communications Client API has just shipped and is now available externally at http://www.microsoft.com/downloads/details.aspx?FamilyID=82c468da-3294-4ca9-bbcc-d455cfd06af2&displaylang=en This API has two acronyms - UCCA and UCCP. I have been calling...

Check out UCForums
Recently I have received several e-mails asking for help and advice for building OCS applications. While I normally do try to take the time to answer these to the best of my ability, with coding speeding up and more deadlines to make it seems unlikely that I will have a lot of spare time in the next...

Some common UCMA questions
Every once in awhile (though somewhat more commonly now) I receive an e-mail or IM asking a question on the UCMA API. I decided to post the answers to some of the most common questions. Where can I download UCMA? - The release candidate is at http://www.microsoft.com/downloads/details.aspx?FamilyID...

Connection managers and endpoint types in UCMA
I have a sneaking suspicion that many of you who use UCMA do not truly know when one should use SipPeerToPeerEndpoint vs SipEndpoint and when one should use RealTimeClientConnectionManager vs one of the RealTimeServerConnectionManagers. In this post I will try to clear up some of the confusion here....

What should I use to write Speech Server applications?
Recently, I have seen a few posts on other blogs asking what should one use to create speech server applications. To review, there are four ways to write speech server applications in OCS 2007. 1) Windows Workflow Activities 2) Core API (basically managed code without Workflow activities) 3...

What it's like so far on the OCS core team
Some time ago I wrote about how I moved from the Speech Server team to the OCS core team. Now that I have been on the team for some time, I thought I'd give random thoughts about my perceptions thus far to those on the outside. First, it is a much larger team in several respects. Firstly, there are...

OK, for those of you who follow Microsoft news this will be old news to you, but upon getting back from Israel and catching up on e-mail I read the announcement that we will acquire Parlano. For more info on this, you can read the brief on Parlano's site . Awhile ago when I was at TechEd several customers...
