Features
Service Observing
When a Service Observer activates Service Observing for an extension that is not
active on a call, as soon as a call is answered at that extension, the Service
Observer's telephone goes off-hook on the speakerphone, and the Mute button
turns on. If the Service Observer is using a headset, the headset automatically
connects to the call at the observed extension. If the Service Observer is active on
another call when a call arrives from the observed extension, no notification is
given for the call from the observed extension, and the Service Observer remains
on the active call.
Feature code activation is not supported since the Service Observer button is
programmed by Centralized Telephone Programming. If a Service Observer
wishes to change Service Observing groups or any other status of the extension,
the change must be made through Centralized Telephone Programming.
NOTE:
Service Observers must be programmed through Centralized Telephone
Programming to prevent random extension observing by unauthorized
extensions. A Service Observing button cannot be copied.
The Service Observer is dropped from a Service Observing call if:
The far-end extension hangs up.
The observed extension hangs up.
The observed extension transfers the call.
The Service Observer hangs up.
Another extension bridges onto the call, thus making the total of local
switch extensions more than two.
The Service Observer station uses headset hang-up.
Programming a Service Observing Station/Group
Programming a Service Observing button on an MLX telephone to create a
Service Observer must be done through Centralized Telephone Programming.
Three main programming menus are used to:
Select and enable Service Observers.
Turn off the warning tone option for the group (factory setting is On).
Specify the members of the Service Observing group.
See the System Programming guide for complete information about programming
Service Observers and groups.
NOTE:
You may turn off the warning tone only if the local jurisdiction does
not require one.
