VOIP Call Coder Type and Noise Report

Introduction

It is essential to network administrators today to track each call’s VOIP Noise and ACOM levels. They are interested in creating *true* and *functional* VOIP Call ‘Service Level Agreements’. This is a significant improvement over current Synthetic Voice based SLA’s as it allows the actual Call to be evaluated in terms of meeting the intended Call’s SLA for Noise quality.

Solution Overview

This could be done by testing the value of the MIB Objects ‘cvCallHistoryNoiseLevel’ and ‘cvCallHistoryACOMLevel’ against a pre-determined and acceptable noise and ACOM levels calculated per actual Call in a production environment.

SOSL based Management Process script configuration

MODULE  cCallHistoryData();

BEGIN

          ALL-DEV (ZONE "entL3") BY DEV                  

          {                 

                   SET-INDEX cCallHistoryTable

                           (cvVoIPCallHistoryConnectionId [cCallHistoryIndex, INT]);

                   WITH-INDEX cCallHistoryTable

                   {

                             POLL (cvVoIPCallHistoryRemoteIPAddress;

                                    cCallHistoryPeerAddress;

                                    cCallHistoryCallOrigin;

                                    cvCallHistoryCoderTypeRate;

                                    cvCallHistoryNoiseLevel;

                                    cvCallHistoryACOMLevel );

                   };

           };
