Overview#
At 2:14 a.m. on a Saturday, three calls come in simultaneously: a cardiac arrest on the highway, a house fire in a residential block, and a reported stabbing at a bar. The dispatcher on duty has to triage all three in seconds, assign the right units, and keep every caller on the line. The PSAP Dispatcher Operations module is built for exactly that moment.
The PSAP module is the operational core of the Argus platform for 911 emergency call handling. It gives dispatchers a unified, intelligence-driven interface covering AI-powered call triage, real-time transcription and sentiment analysis, Standard Operating Procedure automation, callback deflection, dispatcher wellness monitoring, surge management, multi-agency coordination, and multi-channel communication. Rather than reacting call by call, dispatchers are supported from the first ring to incident close with context, protocol guidance, and cross-agency situational awareness.
Key Features#
- Call Handling Interface: Priority-based call queue (P1-P5) with live call controls, caller information display, and real-time transcription for efficient emergency call management
- AI-Powered Classification: Automated call classification with urgency scoring, threat assessment, and recommended response levels based on call content analysis
- SOP Automation: Standard Operating Procedure management with automatic trigger matching across 8 trigger types, ensuring dispatchers follow correct protocols for each incident type
- Callback Deflection: Queue management for non-emergency callbacks, reducing dispatcher workload during peak periods and ensuring emergency calls receive priority attention
- Dispatcher Wellness Monitoring: Fatigue tracking, stress indicators, and wellness alerts to protect dispatcher well-being during extended or high-intensity shifts
- Surge Management: Automated staffing adjustments and call routing optimisation during mass casualty events, severe weather, and other high-volume scenarios
- Multi-Agency Coordination: Dispatch coordination across police, fire, EMS, and specialized agencies with shared incident information and resource tracking
- Multi-Channel Support: Voice, SMS, web, and video communication channels for NG911 / NG112-compliant emergency communications
Use Cases#
- Emergency Call Processing: Handle 911 calls with AI-assisted triage, real-time transcription, automated priority assignment, and SOP-guided response protocols
- Mass Casualty Event Management: Activate surge protocols during major incidents with automated call routing, staffing escalation, and multi-agency notification
- Non-Emergency Management: Route non-emergency calls to appropriate queues with callback scheduling, reducing dispatcher load and improving emergency call response times
- Dispatcher Support: Monitor dispatcher workload, wellness indicators, and performance metrics to maintain effective staffing and prevent burnout during demanding operations
- Quality Assurance: Review call handling with transcription records, SOP compliance tracking, and performance analytics for training and continuous improvement
Integration#
The module integrates with CAD systems for unit dispatch, radio networks for field communication, mapping services for location intelligence, and multi-agency coordination platforms. Supports NG911 / NG112 standards for multimedia emergency communications across 911 and 112 centres, emergency communications centres (ECCs), police dispatch operations, fire and rescue, and EMS coordination.
Open Standards#
- NENA i3 (NENA-STA-010 / STA-012): The dispatcher interface routes all incoming calls through the NENA i3 Emergency Services IP Network architecture, consuming Emergency Incident Data Objects (EIDO) from CAD and exchanging SIP-based call control with Emergency Service Routing Proxies (ESRP) for NG9-1-1 and NG112 centres.
- PIDF-LO (RFC 4119 + RFC 5491): Caller location delivered on every screen pop is parsed from Presence Information Data Format Location Object XML, providing civic and geodetic coordinates used in priority classification and unit dispatch.
- LoST, Location-to-Service Translation (RFC 5222): The routing engine queries an Emergency Call Routing Function via LoST to translate the caller's location and service URN (RFC 5031 / RFC 6443) into the correct PSAP boundary and responsible agency for dispatch.
- RFC 7852, Additional Data for Emergency Calls: Structured caller-enrichment blocks are retrieved from the Additional Data Repository at call-answer time, populating the dispatcher screen pop with subscriber, provider, and device information.
- SIPREC, SIP Recording (RFC 7865 / RFC 7866): All call audio is captured via SIPREC session metadata and media recording, enabling the quality-assurance and playback features that supervisors use for training and SOP-compliance review.
- ITU-T T.140 / RFC 4103: Real-Time Text sessions between deaf or speech-impaired callers and the dispatcher console are carried as T.140 character streams over RTP (RFC 4103) with RFC 2198 redundancy, fulfilling the Text-to-911 channel requirement.
- OASIS Common Alerting Protocol (CAP) 1.2: Surge and mass-casualty notifications egressed to IPAWS are signed and published as CAP 1.2 messages, allowing the dispatcher to broadcast authenticated public alerts from within the same interface.
- APCO Project 25 (P25): Radio talkgroup dispatch to field units uses Project 25 digital radio protocol, enabling interoperable voice coordination across police, fire, and EMS agencies on shared P25 networks.
