Check "1 call" to keep the factory setting.

External Alert for Calls-in-Queue Alarm allows group members to be notified by
an external alert when calls waiting in the queue are equal to or greater than the
programmed threshold. The alerting signal remains active until the number of
calls in the queue drops below the threshold.
Note: Since the signal is continuous, it is recommended that only lamp-type
external alerting devices be used.
The external alert designated for Calls-in-Queue Alarm can be any alerting
device connected through a Multi-Function Module (MFM) in the External Alert
mode for digital/lSDN (MLX) telephones. Only one external alert can be
designated for each calling group.
Note: An alert connected to a Supplemental Alert Adapter (SAA) for an analog
multiline telephone should not be used as a Calls-in-Queue Alarm.
