Comtech Telecommunications Corp. [NASDAQ: CMTL]
Connecting Emergency Calls to the Information that Matters

An emergency call is only the beginning of a response. The information accompanying that call, the location and the ability to reach the appropriate public safety answering point (PSAP) determine how effectively an emergency communications center can act. For agencies replacing conventional 9-1-1 infrastructure, the challenge extends beyond answering calls to ensuring that information moves reliably between networks and personnel.

Comtech Telecommunications Corp. [NASDAQ: CMTL] navigates this challenge through an integrated Next Generation 9-1-1 technology portfolio that connects emergency call routing with multimedia call management. Through its Guardian solutions and Next Generation Core Services (NGCS), it enables public safety agencies to receive calls across different communication formats while accessing location information and incident data within their existing workflows.

Modernizing the Emergency Communications Infrastructure

Comtech's approach starts at the network level, where emergency calls should travel from originating service providers to the appropriate PSAP. Its NGCS platform provides the infrastructure required to replace legacy selective-router-based networks with IP communications capable of supporting evolving emergency services.

The platform connects originating networks with emergency communications centers through an emergency services IP network (ESInet). It supports end-to-end IP call routing and location-based routing while accommodating traditional network connections during migration. This allows jurisdictions to introduce next-generation capabilities without requiring an immediate replacement of every existing component.

A critical part of this transition is converting time-division multiplexing traffic into IP communications. Comtech's media conversion gateways maintain connectivity with older network infrastructure, allowing agencies to continue handling conventional emergency calls while preparing their systems for multimedia information exchange.

NGCS also incorporates an emergency call routing function that uses geographic information system data to determine routing instructions. A location validation function checks location information against geographic reference data, helping the network process location-based emergency call routing according to established technical standards.

The architecture combines active-active processing with geographic redundancy and automated failover capabilities. Redundant central components distribute processing loads and maintain alternative paths when system components become unavailable. This design supports emergency communications continuity without depending on manual intervention during a system failure.

Bringing Multimedia Intelligence to Emergency Call Handling

Once a call reaches an emergency communications center, Comtech's Guardian Call Handling platform provides the interface through which call takers receive and manage incoming information. The system supports traditional voice calls alongside text communications and multimedia data, bringing different communication formats into a purpose-built emergency management environment.

The platform enables personnel to answer calls, transfer conversations and establish conferences while gathering information relevant to an incident. Its integrated call control architecture reduces the need to manage each communication type through an entirely separate application.

Guardian Messenger extends this functionality to text-based emergency communications. Incoming text-to-911 sessions appear within the call-handling environment and can be managed using functions associated with voice calls. Personnel can transfer or join text sessions, while outbound text-from-911 functionality provides another communication channel when additional information should be exchanged.

Guardian Map provides location information, showing the geographic position and status of emergency calls through an interactive mapping interface. Call takers can see location details and manage calls straight from the map rather than relying exclusively on textual coordinates.

The mapping application supports locally hosted geographic data and configurable base maps. Its three-dimensional location capabilities provide additional geographic context for personnel examining incoming incidents. This integration connects location intelligence with call management, giving emergency communications centers a more complete view of information associated with each call.

Flexibility across Networks and Jurisdictions

A distinguishing aspect of Comtech's emergency communications portfolio is its support for multiple deployment configurations. Public safety agencies differ in their existing infrastructure and available technical resources. Comtech accommodates these requirements through hosted, dedicated managed-service and hybrid NGCS deployment models.

Under the hosted model, Comtech operates NGCS infrastructure within redundant, geographically distributed data centers. The arrangement allows agencies to access next-generation routing capabilities without maintaining the complete underlying infrastructure themselves. It also provides a deployment path for jurisdictions looking to limit initial capital expenditure.

The dedicated model places infrastructure within the customer's region while Comtech manages the associated software services. Hybrid deployments connect elements of hosted and locally installed infrastructure. These alternatives allow agencies to select an architecture compatible with their technical requirements and implementation priorities.

The flexibility extends to interoperability. Comtech's NGCS supports National Emergency Number Association i3 standards and interfaces with compatible call-handling equipment. Its modular architecture allows different system components to communicate through established technical interfaces rather than requiring every participating application to originate from one supplier.

The approach is reflected in Comtech's work through its Allerium, a public safety technology business segment, with the 911 Association of Central Oklahoma Governments. The partnership supports 22 emergency communications centers serving more than 740,000 residents. In March 2026, the organization chose Allerium to expand an existing call-handling relationship through deployment of an ESInet and NGCS infrastructure.

The agreement extends the relationship for at least five additional years and establishes a path toward IP-based emergency call routing across the participating region. It demonstrates how an established call-handling deployment can evolve into a broader emergency communications network without abandoning the existing partnership.

Extending Information Access and System Reliability

Comtech also provides Guardian Insights, a call logging and reporting application designed to collect multimedia emergency communications information. The platform captures voice recordings alongside associated text and visual data, allowing authorized personnel to examine information generated during call-handling activities.

Its reporting interface supports custom queries and includes 25 predefined report templates. Agencies can modify these to examine specific information, providing administrators with structured access to call records without requiring every report to be developed independently.

Reliability also depends on protecting the systems that process emergency communications. Guardian Managed Services provides cybersecurity monitoring, risk assessment and remediation assistance for public safety environments. These services supplement the resilience built into Comtech's communications infrastructure.

Its newer Allerium Mira platform introduces cloud-native, microservices-based call handling. The architecture supports deployment across shared, private, hybrid and edge environments. Mira is designed to work alongside NGCS and ESInet infrastructure, extending deployment flexibility into the emergency communications center itself.

Together, these capabilities establish a connected approach spanning emergency call routing, multimedia information management and system resilience. Comtech's existing deployments and continued product development demonstrate its emphasis on reliable communications infrastructure that can accommodate changing agency requirements.

Comtech’s recognition as the Top Emergency Communications Technology Provider 2026 reflects the practical capabilities it brings to public safety organizations managing emergency communications.
