A slow flashing red lamp on an appearance button indicates an alerting call. This may also be accompanied by ringing and by the message lamp flashing.
•Note: This guide assumes that auto hold is enabled (the default). The system administrator can disable auto hold for the system, in which case calls are automatically disconnected rather than held.
