Solution’s Traps, Alarms, and Thresholds:
 

A Wide range of reports could be generated by further elaborating on the values of the objects polled in Module cCallHistoryData. The following are suggested  formats for the VOIP Calls Alarms and Threshold points:

Calculating actual time to establish the Call:

This is the result of subtracting the value reported by cCallHistorySetupTime From cCallHistoryConnectTime for each Call and finding those calls with large setup times.

Calculating the ratio of Voice traffic to total traffic in a Call:

This is possible by dividing the value of cvCallHistoryVoiceTxDuration by the value of cvCallHistoryTxDuration. This allows to calculate the Voice Utilization rate to the total transmission rate.

Calculating the ratio of Fax traffic to total traffic in a Call:

This is possible by dividing the value of cvCallHistoryFaxTxDuration by the value of cvCallHistoryTxDuration. This allows to calculate the Fax Utilization rate to the total transmission rate.

Creating *true* and *functional* VOIP Call ‘Service Level Agreements’:

This could be done by testing the value of the MIB Object cvVoIPCallHistoryRoundTripDelay against a pre-determined and acceptable round delay calculated per actual Call in a production environment. 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.

Monitoring the ACOM and Noise Levels:

This is done through direct tracking of each call’s VOIP Noise and ACOM levels. This helps administrators 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.
