Running a growing VoIP operation should not mean adding another tool every time the network expands. Class 4 Fusion reduces operational complexity by bringing routing, switching, billing, monitoring, reporting and operator workflows into one connected telecom platform. (DeNoVoLab)
For telecom operators the real challenge is often not traffic volume alone. It is the number of systems and processes required to manage that traffic. Carrier rates need to be maintained, routes need to be controlled, customer billing needs to remain accurate and network performance needs continuous monitoring. When these functions are separated across multiple platforms the operational workload can grow faster than the network itself.
DeNoVoLab Class 4 Fusion takes a different approach by positioning the Class 4 switch as an all-in-one operator platform for termination and origination traffic. It combines core network functions with billing, portals, reporting and automation so operators can manage more of their daily workflow from one environment. (DeNoVoLab)
Consolidating Core Telecom Functions Into One Platform
The problem with disconnected systems
Consider a telecom operator using separate applications for switching, routing, billing, CDR analysis and customer management. A simple question such as “Is this route profitable?” may require information from several systems.
That creates administrative friction.
DeNoVoLab describes Class 4 Fusion as a platform that combines switching, routing, billing, monitoring, reporting, backup and operator workflows. Its current feature set also includes rate generation, CDR and PCAP backup plus customer and vendor portals. (DeNoVoLab)
The advantage is similar to replacing several separate control panels with one central operations console. Instead of repeatedly transferring information between systems operators can work with connected workflows.
One platform creates a broader operational view
An earlier DeNoVoLab technical document describes a data-centric architecture where modules operate on a common data set. It specifically describes a 360-degree view of partner activity across finance, network and routing operations. (DeNoVoLab)
For example customer billing information can be considered alongside traffic activity rather than being isolated from the network operation.
That connection is particularly useful when the same event affects multiple departments.
Simplifying Routing and Switching Administration
Centralized route control reduces manual configuration
Routing can become complicated quickly when an operator manages multiple vendors, destinations and trunks.
Class 4 Fusion provides LCR and prefix rules, trunk groups, failover and margin-aware control. Its switching environment also includes high-CPS call handling plus SIP trunk operations and channel limits. (DeNoVoLab)
Instead of maintaining separate routing logic for different parts of the operation an administrator can manage these controls within the Class 4 environment.
For example an operator with several termination vendors can establish routing policies around destination prefixes and available trunk groups then use failover when the preferred path becomes unavailable.
Routing and switching work together
This integration matters because routing determines where traffic should go while switching determines how that traffic is processed.
When those functions are managed independently administrators can spend time reconciling configurations. Bringing them together reduces the number of operational handoffs.
The result is not simply fewer screens. It is fewer disconnected decisions.
Automating Rate Management and Routine Work
Rate administration can consume significant time
Carrier rate decks are an important part of wholesale voice operations. When rates change across many destinations and vendors manual updates can quickly become repetitive.
Class 4 Fusion includes automated rate generation and the platform describes automated rate generation, fraud blocking, archive automation, reporting and invoicing as part of its operational automation. (DeNoVoLab)
DeNoVoLab's technical documentation also describes automatic rate delivery, route testing and rate import. (DeNoVoLab)
Imagine an operator managing hundreds of carrier updates. Without automation each update becomes another administrative task. With automation the system can handle defined processes while staff focus on exceptions and decisions that actually require human attention.
Automation turns administration into supervision
The goal is not to remove administrators from the workflow. It is to move their role from repetitive execution toward oversight.
Instead of manually processing every routine rate update an administrator can review the results, investigate unusual changes and focus on carrier strategy.
This becomes increasingly valuable as traffic and vendor relationships expand.
Connecting Billing With Network Operations
Billing should not operate in isolation
Billing is one of the areas where fragmented systems can create significant operational complexity.
Class 4 Fusion includes rate decks, invoices, balances, credit limits and customer and vendor billing within its billing environment. (DeNoVoLab)
That means the commercial side of the business remains closely connected to the network operation.
For example a customer can generate substantial traffic while approaching a configured credit limit. When billing and switching are connected the operator has a more direct operational relationship between traffic and financial controls.
CDRs create a common operational reference
Call Detail Records provide another connection between network and business activity.
Class 4 Fusion includes CDR management and PCAP backup as part of its operator platform. (DeNoVoLab)
An administrator investigating a customer billing question can therefore examine the underlying traffic information instead of treating the invoice as an isolated financial record.
This is similar to having both the invoice and the original transaction record available within the same system.
Reducing Administrative Load Through Self-Service
Customer portals reduce routine support work
Operational complexity is not limited to internal teams. Customers and vendors generate information requests that can consume administrative resources.
Class 4 Fusion provides a Client Portal with self-service accounts, invoices, payments and usage reports. (DeNoVoLab)
This allows customers to access routine information directly rather than depending on an operator to generate every report manually.
For example a customer looking for recent usage can retrieve the relevant information through the portal instead of opening a support request.
Vendor management can follow the same model
The Vendor Portal provides supplier rates and CDRs alongside vendor invoices and traffic settlement workflows. The Agent Portal adds customer access, commission workflows and sales channel reports. (DeNoVoLab)
This creates separate operational paths for different stakeholders while keeping them within the same broader platform.
The result is a more structured division of responsibilities without requiring a separate application for every relationship.
Monitoring and Automation Reduce Reactive Administration
Visibility can prevent small issues from becoming larger tasks
Network administration becomes more difficult when teams only discover problems after customers report them.
Class 4 Fusion integrates monitoring into its broader operating environment and includes automated operational functions. The platform also positions routing, billing, monitoring and fraud controls within one switch workflow. (DeNoVoLab)
This allows administrators to work with network information while managing the surrounding operational processes.
For example a change in traffic behaviour can be investigated through the same environment used for routing and CDR analysis rather than requiring several unrelated systems.
Automation provides operational consistency
A useful way to think about automation is as a standard operating procedure executed consistently by software.
Rate generation, reporting, invoicing and fraud blocking are examples of processes that can otherwise require repeated human intervention. DeNoVoLab identifies these functions as part of Class 4 Fusion's automated operations. (DeNoVoLab)
When traffic volumes increase the benefit becomes more significant because the number of repetitive tasks can rise rapidly.
Scaling the Operation Without Scaling Complexity
Growth should add traffic without multiplying tools
DeNoVoLab currently offers a 500-port Community Edition for live-traffic evaluation and supports deployment on servers, VMs, AWS and Google Cloud. Its commercial model allows operators to scale beyond the Community Edition. (DeNoVoLab)
The platform also states a vendor figure of 42k CPS and describes its switching experience as 99.999% SLA-oriented. These are vendor-stated figures rather than universal performance guarantees and actual results depend on deployment and traffic conditions. (DeNoVoLab)
The operational point is broader than capacity.
If every increase in traffic requires another billing system, another monitoring tool and another routing workflow then growth creates additional administrative complexity. An integrated platform can provide a more consistent operating foundation as the network expands.
Cloud and self-hosted deployment add flexibility
Class 4 Fusion supports server, VM, AWS Marketplace and Google Cloud Marketplace deployment options. (DeNoVoLab)
That allows operators to choose an infrastructure model that matches their existing environment rather than redesigning the entire deployment around one mandatory architecture.
How Class 4 Fusion Compares With Other Telecom Platforms
PortaSwitch uses a unified service-management model
PortaSwitch is also positioned as a unified telecom platform. Its architecture combines PortaBilling for real-time billing and service provisioning with PortaSIP for Class 4 and Class 5 SIP switching. PortaOne describes routing information as being connected directly with billing so termination costs can be considered during route selection. (PortaOne Documentation)
PortaOne also provides an open architecture designed to integrate with third-party applications and simplify tasks such as customer activation and rate management. (PortaOne Documentation)
The distinction is primarily in product positioning and architecture. PortaSwitch is a broad converged service-management platform while DeNoVoLab positions Class 4 Fusion specifically around the Class 4 operator workflow with routing, switching, billing, monitoring, CDR management, portals and automation in one operating environment. (DeNoVoLab)
TelcoBridges focuses strongly on the SBC layer
TelcoBridges ProSBC takes a different approach with a strong focus on the Session Border Controller layer. Its platform provides flexible call routing, web-based management, topology hiding and high-availability configurations. (TelcoBridges)
TelcoBridges also offers Monitoring as a Service with real-time dashboards, threshold alerts and monitoring of network performance and security events. (TelcoBridges)
Its hosted SBC offering states support for up to 60,000 concurrent sessions per server and up to 1,024 trunk groups. (TelcoBridges)
The architectural difference is important. ProSBC is centered on SBC functionality and voice-edge management while Class 4 Fusion brings switching together with routing, billing, portals, CDRs, reporting and operator automation. (DeNoVoLab)
For an operator evaluating platforms the relevant question is therefore not simply which product has more features. It is which operating model matches the network's requirements.
Conclusion: Reduce Complexity by Connecting the Operation
Telecom growth should not require teams to manage an ever-expanding collection of disconnected tools. When routing, switching, billing, monitoring, reporting and stakeholder management are separated the administrative workload can grow alongside traffic.
DeNoVoLab Class 4 Fusion addresses this challenge by combining these functions within one Class 4 operating platform. Its current capabilities include intelligent routing, switching, billing, monitoring, CDR and PCAP backup, automated rate generation, customer and vendor portals plus API integration. (DeNoVoLab)
The result is a more connected operational model where teams can manage network traffic and business workflows from the same environment.
For telecom operators the objective is straightforward: fewer disconnected processes, less repetitive administration and greater visibility across the entire voice operation.
