OCS 2007 R2 Workload Poster Update

6 May 2010

Back on the 25th January 2010 I blogged about the OCS Architecture poster being available for download. Last month there was an update to correct some of the minor errors on it. So make sure you update your copy from the same location.

Although it isn’t 100% comprehensive is does give a great overview which you can share with customers.

Disable the CX700 (Tanjay) Inactivity Phone Lock

1 May 2010

Recently I have been asked about how to stop the Polycom CX700 from automatically locking after the default 10 minute period of inactivity. This is particularly important where the phone is in a shared area and therefore you do not want the people to have to key in the pin code before being able to dial.

Fortunately this is easy to do. On the Pool Front End properties go to the Voice tab. Here you can untick the Enforce phone lock or alternatively change the timeout period and PIN length (note that the shortest pin allowed is 4 digits).


The only caveat with this change is that it is now no longer possible to even lock the phone manual either from the phone or if you have the USB connection then locking your PC will no longer lock the phone. If you need to secure your phone when you are away you will now need to sign out of the CX700.

OCS with Microsoft Dynamics GP 2010

1 May 2010

Applications integrated with OCS to leverage the power of presence is really good news for everyone. Customers using Dynamics GP 2010 can see the presence of contacts within the product. Obviously it requires Federation to enable cross business presence but this is a great driver to bring even more emphasis on B2B unified communications.

Below is screen shot from the Microsoft Dynamics GP Product blog which also discusses the features in a little more detail. http://blogs.msdn.com/gp/archive/2010/03/30/feature-of-the-day-unified-communications.aspx


What sort of Certificate Authority am I running?

15 April 2010

One of the requirements when setting up OCS with RCC for the Avaya PBX is you need to have a Enterprise CA running on Windows 2003 Enterprise or 2008 Enterprise.

Quite often I find if the customer isn’t using the CA extensively in their environment they are not sure how the CA was installed.

An easy way to tell is to run certutil –cainfo from the command line and you can ask the customer to run this in advance of arriving on site. You can see below the output for a rootCA


Wave 14 OCS functionality

31 March 2010

A very interesting article on Adam’s UC Blog. As part of VoiceCon 2010 PBX vendors were asked to respond to hypothetical RFP. Microsoft was chosen as the winning vendor and their response can be downloaded from here. The responses indicate some of the feature we can expect with Wave 14

I won’t repeat Adam’s excellent interpretation of the features that can be assumed from RFP response as you can read it here.

Some of the features may not make it to the final product and it is obviously not a comprehensive list of features just possibilities from the RFP but it does give a good insight into what we can expect.

OCS2007R2 Supported on Windows 2008R2

31 March 2010


Microsoft had scheduled support for OCS on Windows 2008R2 in 1Q2010. On the last day of the quarter we finally have confirmation of support.

There are a few still a few issues, Group Chat support being the main one.

Support is also only for new installations of Windows 2008 R2 you cannot upgrade an existing OCS 2007R2 system.

Two knowledge base articles have been released

When you upgrade a domain controller to Windows 2008 R2 x64 OCS does not function correctly. To fix this you need to rerun the ForestPrep.  Full details are in this knowledge base article 982020

For full details and the process required to install and prepare Windows 2008R2 for OCS look at the knowledge base article 982021

Microsoft OCS 2007 R2 Workload Poster

25 January 2010

Microsot have recently released a Workload Architecture poster showing protocol flow, ports, DNS and Certificates. It gives a graphical representation of information found in the various OCS manuals all in one place.

This poster only shows the IM & Presence, Conferencing, Application Sharing and Enterprise Voice Worloads. However it does show everything for internal and also external access through an Edge Server.
