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 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 took a few pictures of some of the phone I have around the house.
I have a few Cisco 7960’s, a 7920, and a Polycom 501 I use regularly around the house. In case you are wondering what the VR button does on my phones. I have Mister House running to control my lights and other stuff around the house, and that button is a speed button for my speech recgonition server. I will write more on this later.
I have been running a VoIP network for just over two years now. It started out with Asterisk [http://www.asterisk.org] but a few months ago I rolled out my 2nd generation voip network using OpenSER [http://www.openser.org]. There was a few reason for the change first was scaleability and redundancy, the second was bandwidth, or media path issues. When I used Asterisk the media path for all calls came through me, now they go endpoint to endpoint. The biggest challenge with that was nat, which is one of the main resons I want to see IPv6 take off. Read more for more on NAT and SIP.
