2-210 Inspect
Any MLX telephone user can inspect the number of calls in the calling group
queue by pressing Inspect and then pressing a button programmed with the
calling group's extension. The display shows the label associated with the
calling group and the number of calls.
If the user presses the Hold button while Inspect is activated, Inspect is
canceled and the system tries to put the call on hold.
If the user gets a voice-announced inside call or a Group Speakerphone Page
while using the Inspect feature, the inspect feature is canceled and the user is
returned to the Home screen.
When a conference participant joins a conference by using a shared outside line
or Shared System Access button, the QCC display reflects the correct number
of participants. However, if the QCC system operator uses the inspect feature to
verify the number of participants, the number on the display does not include
participants joining the conference on a shared button.
If a QCC system operator presses any of the buttons programmed with fixed
QCC features (for example, a Call, Start, or Source button) while in the Inspect
mode, the console remains in Inspect mode. However, if the operator presses
the Feature, Transfer, HFAI, Conf, Mute, Drop, Speaker, or Hold buttons, the
console is removed from the Inspect mode.
If a user presses the Transfer button while inspect is activated, inspect is
canceled and the user is returned to the Home screen.
