8.2-12 Integration Volume
However, if internal callers want the ability to use the Busy Standby Queuing or the Call Waiting feature
on a busy extension, the ROLM Model 30/80 CBX should be programmed not to forward internal calls
on a busy condition. Internal callers may then use the feature, but will not have call coverage to the Octel
200/300 when the called station is busy.
In order to have a visible message waiting indicator, digital phones must be configured to have a message
waiting key (MW), and analog phones must be connected to a ROLM message waiting line card.
