Lync and Exchange 2007 UM integration

Recently I was deploying a new Lync environment but was asked to integrate with Exchange UM 2007. All the blogs I had come across before dealt with either OCS 2007 (R2) and UM 2007 or Lync 2010 and UM 2010…

For the most part I was able to follow the Exchange UM 2007 Deployment guide that was available with OCS and the Lync UM guide for the Lync bits. The problem as I recall with UM 2007 was that the naming convention of the UM Dial Plan had to match the location profile on OCS.

Only thing is that Lync no longer has location profiles, these have been replaced with Lync Dial Plans. So wanting to check both of these proverbial boxes I created a Lync Dial Pan named the same as the UM Dial Plan.

When Running the OCSUMUtil you can see the Lync Dial Plan naming and so correct it accordingly.

Once that was a match I no longer got the error about the Dial Plan for exchange 14 bla bla

One final adjustment was to add a normalization rule to this Lync Dial Plan to allow for calling to the UM and voila.


About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
