apCodecPairStatsTable
This table, found in the ap-codec.mib, provides a listing of all unique codec pairs currently being transcoding and the session count of that pair currently in use. It conveys the same information displayed in the show xcode codecs command. Use the apCodecTable for correlation between Codec name (apCodecName) and Codec index (apCodecIndex) to define apCodecPairAIndex and apCodecPairBIndex. When Ptimes for call legs in the codec pair differ, they will be included as additional indices. When digit translation is active on the call and digit translation types differ across call legs, indication of which call leg uses which digit translation type is output as well. Use the ApCodecDigitTypes object for digit type value correlation.
