Full IP PBX Functions for Daily Operation
The system provides complete IP PBX capability for normal business communication inside transportation facilities. Control rooms, station offices, service desks, maintenance teams, security posts, and operation departments can be connected through a unified extension plan.
Staff can make internal calls, receive external calls through SIP trunks, transfer calls between departments, use IVR menus for service hotlines, manage call queues for passenger service, and set ring groups for different teams. Call recording and call logs help managers review service quality and communication records when needed.
Zone-Based Mass Notification
Transportation sites need messages to be sent by area, not always to the whole facility. The system supports zone-based broadcasting, allowing operators to divide a site into platforms, halls, tunnels, terminals, gates, entrances, parking areas, offices, maintenance zones, and outdoor areas.
A delay notice can be sent only to one platform. A gate change message can be played in a selected terminal area. A maintenance warning can be sent to staff-only zones. In an emergency, the control room can broadcast to all areas with higher priority.
Emergency Voice Broadcasting
For fire alarms, tunnel accidents, security incidents, equipment failures, severe weather, evacuation events, or traffic disruptions, the system can deliver urgent voice messages quickly. Emergency announcements can be configured with higher priority, so critical instructions are not blocked by normal calls or routine broadcasts.
Operators can use live voice, pre-recorded messages, or predefined emergency plans. For example, a tunnel control room can trigger accident warning messages, while a metro station can play evacuation guidance to platforms and exits.
Pre-Recorded Messages and Live Announcements
Daily transportation operation often uses repeated messages, such as safety reminders, passenger guidance, service delay notices, platform instructions, parking notices, and maintenance warnings. The system supports pre-recorded message playback to make these announcements consistent and easy to operate.
When a situation changes, authorized staff can make live announcements from the dispatch center, station office, control room, or approved SIP extension. This allows fast manual communication without losing central control.
SIP Intercom and Passenger Help Points
The system can connect SIP emergency intercom terminals, passenger help points, industrial telephones, IP phones, and service desk phones. When passengers, drivers, or field staff need help, they can call the control room or service center directly.
Incoming calls can be routed through IP PBX rules. They can enter a call queue, ring a selected team, be transferred to another department, or be recorded for later review. This makes the system useful not only for broadcasting, but also for two-way emergency communication and service response.
Dispatch Center Control
The dispatch center can manage calls, announcements, notification zones, device status, emergency plans, and communication records from a central interface. For multi-site transport networks, headquarters can manage several stations, tunnels, or terminals while local teams keep control of daily operation.
This structure is suitable for railway lines, metro networks, airport terminals, port areas, highway tunnel groups, and regional transit systems.
Alarm Linkage and System Integration
Transportation safety often depends on more than one system. The system can work with fire alarm systems, CCTV platforms, access control, tunnel monitoring, security systems, and operation management platforms through suitable interfaces.
When an alarm is triggered, the system can start a predefined voice message, notify selected zones, alert responsible teams, or remind operators to take action. This helps reduce manual delay during urgent events.
