UM Tools – Call Statistics


Found an interesting item in the UM Exchange Management Console – Toolbox.

The Call Statistics gave me a good view of the activity on the UM Server

Calls per day, broken down into fields like Total, Failed and Audio quality. Each with a Hyperlink, when double clicking you get more info on the calls as below.

What is NMOS?
NMOS   The Network Mean Opinion Score (NMOS) score for the call. The NMOS score indicates how good the audio quality was on the call as a number on a scale from 1 to 5, with 5 being excellent.
Note   The maximum NMOS possible for a call depends on the audio codec being used, and NMOS may not be available for very short calls that are less than 10 seconds long.

NMOS degradation   The amount of audio degradation of the NMOS score from the top value possible for the audio codec being used. For example, if the NMOS degradation value for a call was 1.2 and the NMOS reported for the call was 3.3, the maximum NMOS score for that particular call would be 4.5 (1.2 + 3.3).

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.
