Enable Referred By Header

I have often come across a SIP vendor that uses the CLI for billing purposes. This can be an issue when A (External PSTN party) calls B (lync DDI user) which is forwarded or transferred to C (external PSTN party).
In this case the true caller A cannot be shown as the calling party as the SIP vendor cant bill that caller.  In this instance you will find that the vendor supports refered-by headers, not something that is enabled on Lync by default.

On each Mediation server do the following:’
Edit the file MediationServerSvc.exe.config found in C:\Program Files\Microsoft Lync Server 2010\Mediation Server so that it looks as follows:-



In my example I have 2 gateways as shown by the 2 add key lines.
The Mediation Services will need a restart to take effect

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.
