Message Waiting Indicator
One red LED in the center of the CALLMASTER VI serves as a Message Waiting indicator. The lamp lights when a message is waiting.
Note: if this lamp flashes it is an indication that the DEFINITY ECS is not communicating with the CALLMASTER VI.
Call Appearance Buttons
These two call appearance buttons have two lamps each. The green lamp indicates that the line is in use, while the red lamp indicates that there are no calls on the line at the present time.
These buttons are administrable. One suggestion is to configure them as Send All Calls or Call Forwarding buttons for use when the PC goes down.
Release Button
The large blue button has no indicator. Pressing the Release button clears the current call.
This button is administerable, but it is recommended that it be assigned to the Release function.
