•Maximum duration of the record for replay (in ms): OLDCB.GLOBAL.REPLAY.MAXDURATION

Location: TPO Boot Settings
OLDCB	Size of the buffer used for instant replay Key: OLDCB.GLOBAL.REPLAY.MAXDURATION Description: Defines maximum duration of instant call replay in milliseconds. It can not be greater than 5 minutes. This setting allow to decrease buffer size in order to limit TPO system memory usage. Constraint: The value must be between 0 to 300000. Related settings: Instant replay duration 1 (profile.setting.instantreplay.delay.1) Instant replay duration 2 (profile.setting.instantreplay.delay.2) Instant replay duration 3 (profile.setting.instantreplay.delay.3) Instant replay expiration buffer (profile.setting.instantreplay.buffer)

This parameter defines the maximum duration of the record for replay. The default value is  300000 (5 minutes).

WARNING: By changing this value, the administrator must ensure that the related turret's parameters are also adapted.

•Graph sampling rate (in number of samples of 10 ms) : OLDCB.GLOBAL.REPLAY.GRAPHSAMPLING_RATE

This parameter defines the sampling rate to rebuild the voice graph. The default value is 10. It means to rebuild the media engine compute a couple of graph value every 10 samples of 10 ms.
