VOIP Call Performance Errors Report

Introduction

It is essential for network administrators today to track each Call’s VOIP packets performance related errors. They are interested in creating *true* and *functional* VOIP Call integrated into any relevant ‘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 SLA on the one hand and on the other hand it allows the for the broadening of the scope of the SLA’s to include such critical performance metrics.

Solution Overview

This could be done by testing the value of the MIB Objects  ‘cvVoIPCallHistoryLostPackets’, ‘cvVoIPCallHistoryLostPackets’, and ‘cvVoIPCallHistoryLostPackets’ against a pre-determined and acceptable benchmarked VOIP packet performances calculated per actual Call in a production environment.

SOSL based Management Process script configuration

MODULE  cCallHistoryData();

BEGIN

          ALL-DEV BY DEV                  

          {                 

                   SET-INDEX cCallHistoryTable

                           (cvVoIPCallHistoryConnectionId [cCallHistoryIndex, INT]);

                   WITH-INDEX cCallHistoryTable

                   {

                             POLL (cvVoIPCallHistoryRemoteIPAddress;

                                    cCallHistoryPeerAddress;

                                    cCallHistoryCallOrigin;

                                    cvVoIPCallHistoryLostPackets;

                                    cvVoIPCallHistoryLatePackets;

                                    cvVoIPCallHistoryEarlyPackets    );

                   };

           };
