Only one call or monitoring session can be handled at a time. Subsequent calls may disconnect current calls (lower priority) or not connect (higher priority). Priority order: Low: Monitoring, Medium: General calls (lobby to main monitor, monitor to PBX extension), High: Emergency calls. All calls and monitoring sessions disconnect after a programmed "timeout". Optional devices and configuration are required for operations. Contact your building manager for more information.
