PSAP Call Management: 911 Call Handling

Overview#

On a busy Friday evening, a 911 centre handling calls in three languages, with fourteen dispatchers on shift and a queue that jumped from four calls to twenty-two in under three minutes, cannot rely on manual routing decisions. The PSAP Call Management module handles that complexity automatically, directing each call to the right dispatcher in real time.

The module provides intelligent call routing, priority management, and dispatcher workflow tools for 911 emergency call handling. Each call is routed based on dispatcher availability, skills certification, current workload, jurisdictional boundaries, call type, and language requirements. Multi-language routing, real-time workload balancing, and automated escalation keep operations effective whether it is a quiet Tuesday morning or the first minutes of a severe weather event.

Key Features#

Intelligent Call Routing: Multi-parameter routing evaluating dispatcher availability, skills certification, current workload, jurisdictional boundaries, call type, and language requirements for optimal call assignment
Priority Queue Management: Five-tier priority system (P1-P5) with real-time queue monitoring, automatic escalation for aging calls, and dynamic priority adjustment based on evolving incident information
Multi-Language Support: 47 language pairs matched to multilingual dispatchers with automated language detection and interpreter service integration for uncovered languages
Caller Information Display: Instant ANI/ALI presentation with premise history, hazard warnings, known subject intelligence, and previous call records displayed during call connection
Call Transfer and Conference: Seamless call transfer between dispatchers, supervisory monitoring, three-way conferencing for interpreter services, and warm handoff protocols
Queue Analytics: Real-time visibility into queue depth, wait times, abandonment rates, and service levels with automated alerts when thresholds are exceeded
Workload Balancing: Dynamic distribution of calls across available dispatchers based on current load, stress indicators, and skill matching for sustained operational effectiveness
Quality Monitoring: Call recording, supervisor monitoring capability, call scoring frameworks, and compliance tracking for training and quality assurance

Use Cases#

Emergency Call Handling: Route incoming 911 calls to the most appropriate available dispatcher based on incident type, location, language needs, and dispatcher skills and workload
Surge Period Management: Maintain effective call handling during high-volume periods through dynamic routing, priority management, and automated escalation of critical calls
Multi-Language Emergency Response: Connect callers with dispatchers who speak their language or activate interpreter services within seconds of language identification
Supervisory Oversight: Monitor call queues, dispatcher performance, and service levels in real time with tools to intervene, reassign, and adjust routing during operational challenges
Performance Improvement: Analyse call handling metrics, identify training needs, and track quality improvements through comprehensive call management analytics

Integration#

The module connects with telephone systems for call delivery, CAD systems for incident creation and dispatch, language interpretation services, recording systems for quality assurance, and workforce management tools for staffing optimisation. Designed for 911 centres, emergency communications centres, police and fire dispatch operations, EMS coordination, and multi-agency coordination centres.

Open Standards#

NENA i3 Standard (NENA-STA-010 / STA-021 / STA-012): The call management layer is built on the NENA i3 suite, implementing the Emergency Incident Data Object (EIDO) for incident exchange with CAD systems, the Additional Data Repository schema, and the Border Control Function identity model for inter-PSAP call transfers.
IETF RFC 7852 (Additional Data Related to an Emergency Call): The platform implements RFC 7852 in full, fetching and serving the seven standard Additional Data block types (SubscriberInfo, DeviceInfo, CommsInfo, ServiceInfo, OwnerInfo, ProviderInfo, ComponentInfo) to populate the ANI/ALI screen pop at call answer.
SIP Emergency Service URNs (RFC 5031 / RFC 6443): Incoming calls are classified using the RFC 5031 urn:service:sos URI vocabulary (police, fire, ambulance, maritime, mountain rescue, etc.), which drives the priority assignment and skill-based routing decision.
PIDF-LO (RFC 4119 / RFC 5491): Caller location is conveyed in the Presence Information Data Format Location Object, consumed by the routing engine and forwarded to LoST servers during EENA NG-112 call delivery to resolve the responsible PSAP.
LoST Protocol (RFC 5222): The Location-to-Service Translation protocol is used to map a caller's PIDF-LO coordinates to the correct PSAP service URI before routing the call through the Emergency Service Routing Proxy.
SIPREC (RFC 7865 / RFC 7866): All calls are captured via the SIP Recording protocol; segments are Merkle-anchored for tamper evidence and made available for quality assurance, supervisor monitoring, and compliance playback.
ISO 639-1 Language Codes: The 47-language routing matrix and real-time transcription providers both rely on ISO 639-1 two-letter language tags to match callers with multilingual dispatchers or activate interpreter services.
APCO Project 25 (P25) and ETSI TETRA: Radio dispatch talkgroup management supports both APCO-25 digital radio (including Network Access Code assignment) and ETSI TETRA, enabling the dispatcher console to bridge voice calls directly onto first-responder radio channels.
