I created a Message Waiting Indicator (MWI) application for Microsoft Exchange 2007 Unified Messaging. It has been tested with Cisco Communication Manager 6.x but should work with any IP PBX that accepts unsolicited UDP SIP notification.
You can download it Here:

Instalation and Configureation instructions are in the download.
I would love to hear if you have found this usefull and how your are using it. Contact info is in the download.
In a previous post (http://www.mrkernel.net/?p=21) I talked about getting OCPE to work on a different subnet than a domain controller with a WINS server. I have found the solution a while ago and I finally got around to posting it.

I got an iPod Touch and I can blog from it. Sweet.
I have two internet connections coming into my place, and I thought it would be fun to extend my VPN to my friends place to two tunnels with BGP. Our setup looks something like this:

I got a hold of a few OCPE devices. Both the Polycom CX700 http://www.polycom.com/usa/en/products/voice/desktop/cx/communicator_cx700.html and the LG-Nortel 8540 http://www.nortel.com/8540. As anyone who has tried to connect them to Office Communication Server (OCS) 2007 knows, the first thing you must do is get the CA certificate on the phones. Being that they are RTM firmware the official ways of doing this are http://blogs.technet.com/jenstr/archive/2007/11/17/how-to-make-the-root-ca-certificate-available-for-office-communicator-2007-phone-edition.aspx. This works fairly slick except, in my experience, when the phone is not on the same subnet of a domain controller. When the OCPE is factory defaults and on different subnet from a domain controller it is unable to download the certificate. The error I get is “Cannot download certificate because domain is not accessible.”

I installed exchange 12 over the weekend again. 3 times actualy. Almost everything I wanted working except for Outlook 2007 Unified Messaging plug in. I don’t know why I couldn’t get it to work, maybe it is not included in Office 2007 Beta 2. But I was able to call into Exchange and Call out using the webmail interface. However I just watched the following video [http://msexchangeteam.com/archive/2006/05/24/427788.aspx] And it looks like they have a lot more fuctionality, stability and completeness in there current build. Which makes me excited about Exchange 2007 Beta 2. So, I have decided to not expend my efforts with the CTP and wait for Beta 2 before diving in furthur. One thing that would be nice is UDP support in the sip stack.
IPSec in Linux/Unix distrabutions have made great strides in there IPSec implementations. It is now relativly easy to create an IPSec tunnel between two boxes of the same type. For example, [http://www.securityfocus.com/infocus/1859?ref=rss]. But, interoperbility between platforms still requires the user to whild dark the dark magic of IPSec. OpenBSD has a very nice IPSec implementation.Read more for sample config files for a OpenBSD to Linux tunnel

On Friday I installed Vista Beta 2 on my work laptop. I haven’t had a whole lot of time to play with it yet, but my favorite feature right now is the windows+tab feature. It is cool. It is basicly a variant of alt+tab, except in 3Dish. I am actualy impressed so far with the new operating system. I am sure it will definatly be worth the upgrade. We have SA with our microsoft licensing agreement so we are allready ready to go. Are you?
Today just before I left work I downloaded and installed Microsoft Office 2007 Beta 2. I got it through my MSDN Subscription. Allthought I only played with it for all of two minutes, it has a definate Wow factor. Maybe I will post some screen shots of it tomorrow. But, I just wanted to say it is deffantly worth checking out. Also released is Groove, OneNote, and Sharepoint 2007. Microsoft has some pretty cool products coming out. I am interested to see what/if Outlook 2007 Beta 2 has for Unified Messaging support. Maybe I will now resorect my Exchange 12 box.
