KB974571 Breaks OCS 2007 R2
I came back from vacation to find that I was unable to login to OCS. Turns out that an update installed on 10/14 broke the front-end services for OCS. The event log shows the following error:
The evaluation period for Microsoft Office Communications Server 2007 R2 has expired. Please upgrade from the evaluation version to the full released version of the product.
Uninstalling the KB974581 update corrected the problem.
Big thanks to Dietmar Kraume’s blog post at http://tinyurl.com/yjefeg9 for pointing to the solution.

SIP Monitoring with Wireshark
Wireshark is a free tool for capturing network traffic. It is an invaluable resource for troubleshooting problems with VOIP calls. It is available for download from www.wireshark.org (current version for Windows as of this post is 1.05)....

Common Outbound Issues
More developers are starting to work with Office Communication Server 2007 these days. As the community has grown I’ve noticed a number of developers running into a few “gotchas” when working with the OCS outbound calling mechanism. ...

Building Custom Activities Using the Core API
The Speech Server API is interesting to play around with. And understanding how Speech Server works behind the scenes is invaluable in debugging. But the real value of learning the API comes when you decide to build your own custom activities....

Getting Started with the Core API
With the introduction of Voice Response Workflows in Speech Server 2007, Microsoft has greatly simplified voice-enabled application development. The entire process is relatively painless; even downright enjoyable. And for most applications it is all you'll need to build outstanding applications. ...

VoiceXML on Speech Server
Yesterday I posted about an issue with Speech Server and Vista. One reader named Bill asked a question in the comments. My response was a bit long for a comment so I decided to turn it into a separate post instead.
Hey Marc, are you using Microsoft Speech Server with VXML? If so, what hardware are you using on it? Also, does MSS support CCXML?
-BillYes, I'm using quite a bit of VoiceXML. Most of the applications I work on are written to run against the Nuance Voice Platform. I've been using VXML so that I could run them against either platform (or any other platform for that matter).
There are some issues that I ran into where I was using Nuance specific properties (example) that Microsoft doesn't have VXML equivalents for. In those cases I needed to write them using the Speech Server managed model.
The key thing to keep in mind is that Microsoft has implemented the VXML spec pretty much verbatim. So as long as your application is pure VXML you should be fine.
I haven't put Speech Server through any sizing tests so I'm not sure what the hardware requirements will be in the end. That said, my development machine is a DELL D830 with 4GB of RAM running Vista Ultimate. In the lab I'm using a DELL 1950 with 4GB of RAM running Windows Server 2003. In both cases I'm using a Dialogic DMG2000 gateway.
As for CCXML, they don't support it and I don't see that changing. I actually think CCXML is going to go the way of SALT. With only Voxeo supporting a real CCXML implementation I don't think there is going to be a lot of call for it. Also, everything you would want to do with CCXML can be done using Speech Server's Managed API. This is just a guess on my part, I don't have any inside knowledge as to what Microsoft's roadmap looks like.

Notiva
Around 18 months ago I started a new position with Parlance Corporation. I’m proud to say I've delivered my first product - Notiva.
Essentially Notiva is an outbound messaging service which gives developers the ability to add voice, email, and SMS messaging to any application, infrastructure, or architecture with just a few lines of code.
It has been a while since I've last rolled out a completely new product. This has been, without question, one of the most rewarding products I've every worked on. Frankly it has been an absolute blast to work on this.
I'm really excited about Notiva and where it is headed. We're working on the final touches of a full application build on Notiva now. We've already had one partner integrate it into an existing product already.
If you would like to give it a try you can drop me an email or check out www.notiva.com.
