NEC Univerge SV9100 Installation Manual page 18

When you expand the view by clicking the + icon, you can see both legs of the call that is on both
trunks 1 and 31.
If call recording is being used you can playback the calls against either of the call records. The view
can also be filtered by extension number and the recording can still be played back. If call recording
isnt being used then the loopback calls will still be grouped together but the speaker icon will not be
available.
The only limitation to using this feature is that if a loopback is dialled internally that doesn't have a
trunk call associated with it the call isnt displayed correctly in MyCalls. If there is a requirement to dial
loopbacks internally for reporting purposes then PRG 35-02-24, Virtual Loop Marking will need to be
manually disabled in the SV9100 configuration. If the Config Import Tool is ever re-run and modifies
the SV9100 configuration the PRG item will need disabling afterwards.
