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 Read More...

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 Read More...

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 Read More...

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 Read More...

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 Read More...

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 Read More...

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 Read More...

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 Read More...

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 Read More...

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 Read More...

Thoughts on testing speech applications
