ad VQM Active Call Table
1.3.6.1.4.1.664.5.53.5.3.8.1
The adVqmActiveCall table provides detail voice quality statistics on currently active RTP voice streams. A voice call will have two entries in this table one for each active RTP stream. A combination of Source IP Address and Port, Destination IP Address and Port, and SSRC (synchronization source ID) are necessary to uniquely identify the call session. The VQM Active Call table shares the same type of information as found in the Call History table. The VQM Manager transfers the active call statistics into the call history table database when the call completes.
