New York, NY October 20, 2026 –(PR.com)– M5 Technologies Advances Secure Cloud and Enterprise Communications with Mediatrix Sentinel SBC Solutions.

The Canadian telecommunications company, also known as Media5 Corporation, helps businesses and service providers protect telephone calls, connect different communications systems and modernize voice networks with its Sentinel CS, Sentinel 100 and Sentinel 400 solutions.

M5 Technologies, also known by its corporate name, Media5 Corporation, is highlighting its Mediatrix Sentinel portfolio of Session Border Controllers (SBCs), designed to help businesses, telecommunications operators and cloud service providers secure, connect and modernize their voice communications.

As organizations move away from traditional telephone systems toward internet-based calling, cloud communications and platforms such as Microsoft Teams, they face an important challenge: ensuring that calls remain secure, reliable and compatible across different networks and technologies.

The Mediatrix Sentinel portfolio addresses these challenges with three complementary products: Sentinel CS Virtual SBC, Sentinel 100 and Sentinel 400.

What Is a Session Border Controller and Why Do Businesses Need One?

A Session Border Controller, commonly called an SBC, is a specialized telecommunications security and traffic-management system that controls how telephone calls travel between different networks.

In simple terms, an SBC acts like a security checkpoint and traffic controller for business telephone calls.

Just as a network firewall helps protect computer systems, an SBC provides specialized protection for voice communications while helping different telephone systems communicate with one another.

For example, when a company connects its office telephone system to an internet telephone provider or Microsoft Teams Phone, an SBC can help ensure that calls are properly routed, authorized and protected.

An SBC performs several essential functions:

– Protecting telephone communications: Helps prevent unauthorized access, suspicious call traffic and certain network attacks.

– Connecting different telephone systems: Allows compatible equipment and telecommunications platforms from different manufacturers to communicate.

– Securing voice conversations: Supports encrypted signaling and voice traffic to protect communications while traveling across networks.

– Managing telephone traffic: Controls how calls are routed between offices, service providers and cloud communications platforms.

Supporting business continuity: Can redirect communications through alternative connections when primary services become unavailable, provided the required backup infrastructure is configured.

Enabling telecommunications modernization: Helps organizations migrate from traditional telephone infrastructure to modern internet-based voice services without necessarily replacing every existing telephone system.

These capabilities are especially important for businesses that rely on continuous telephone access, including financial institutions, healthcare organizations, government agencies, transportation operators and customer service centers.

Sentinel CS: A Powerful Virtual SBC for Cloud Communications Mediatrix Sentinel CS is a software-based Virtual Session Border Controller designed to operate within virtualized computing environments, either on local infrastructure or in supported cloud environments.

Unlike traditional SBC appliances, which require dedicated physical hardware, Sentinel CS can operate as software on compatible virtual infrastructure.

This provides organizations with greater flexibility when designing, deploying and expanding their telecommunications networks.

According to M5 Technologies’ official technical documentation, Sentinel CS supports configurations of up to 20,000 concurrent SBC sessions and 30,000 registered users, subject to licensing and computing resources.

In practical terms, this means Sentinel CS can support large-scale voice communications environments where numerous telephone conversations take place simultaneously.

The solution includes advanced SIP routing, signaling normalization, network topology hiding, TLS 1.3 security, SRTP media encryption, call admission control, quality-of-service management and network troubleshooting capabilities.

Who can benefit from Sentinel CS?

Telecommunications operators can use Sentinel CS to manage secure connections between their networks and customers.

Cloud communications providers can integrate the solution into hosted voice architectures.

Enterprises can connect multiple offices, remote employees and SIP telephone systems through a centrally managed communications infrastructure.

Managed service providers can also deploy Virtual SBC solutions to help deliver secure business communications to their customers.

Organizations evaluating virtual SBC pricing, cloud SBC infrastructure or an SBC software license can contact M5 Technologies to discuss licensing capacity, technical requirements and deployment options.

Sentinel 100: A Secure Communications Gateway for Small and Medium-Sized Businesses Mediatrix Sentinel 100 is a compact hardware-based Session Border Controller developed for businesses that need secure and reliable telephone connectivity. Supporting up to 120 simultaneous SBC sessions and 500 registered users, Sentinel 100 offers enterprise-grade communication control within a dedicated appliance.

For example, a business operating an existing telephone system may want to connect to a modern SIP trunk provider without completely replacing its current infrastructure.

Sentinel 100 helps establish that connection while providing SIP interoperability, call routing, network security and communications management.

It can also support compatible Microsoft Teams Direct Routing configurations, allowing organizations to integrate Microsoft Teams Phone with their telecommunications infrastructure.

The Sentinel 100 family includes pure SBC and hybrid SBC configurations, supporting different deployment and integration requirements.

For small and medium-sized businesses, Sentinel 100 offers a practical enterprise SBC solution that combines security, flexibility and communications modernization.

Sentinel 400: Combining Advanced Security with Traditional Telephone System Integration Mediatrix Sentinel 400 is a modular telecommunications platform that combines the capabilities of a Session Border Controller, a media gateway and a virtualization server.

Designed for medium-sized and large enterprises, Sentinel 400 supports configurations of up to 2,000 simultaneous SBC sessions and 6,000 registered users.

One of its important advantages is the ability to connect modern IP-based communications networks with compatible traditional telephone systems.

Depending on its hardware configuration, Sentinel 400 supports interfaces including E1/T1 PRI, ISDN BRI, FXS and FXO.

This is particularly useful for organizations operating legacy telephone equipment that cannot immediately be replaced.

For example, a large hotel, industrial facility or government organization may operate a combination of older telephone equipment, modern IP telephones and cloud communications services.

Sentinel 400 can serve as an interconnection and security platform between these systems, allowing organizations to modernize their communications infrastructure progressively.

The platform also offers supported third-party software integration capabilities, providing additional flexibility for specialized telecommunications applications.

Supporting Microsoft Teams and Modern Business Communications
Microsoft Teams has become an important collaboration and communication platform for organizations worldwide.

However, connecting Microsoft Teams Phone to external telecommunications carriers or existing telephone systems can require specialized network equipment or software.

Microsoft Teams Direct Routing enables organizations to connect Teams Phone to compatible telecommunications infrastructure through a certified Session Border Controller.

The Mediatrix Sentinel portfolio supports Microsoft Teams Direct Routing through applicable certified configurations.

This allows businesses to integrate compatible telephone systems, SIP providers and Microsoft Teams environments while maintaining control over their communications architecture.

Deployment must follow the applicable Microsoft certification requirements and supported product configurations.

Addressing the Growing Importance of Voice Communications Security
Telephone systems have become increasingly interconnected with corporate data networks, cloud services and internet infrastructure.

As a result, voice communications require dedicated security controls in addition to conventional network protection.

The Mediatrix Sentinel solutions provide specialized mechanisms for protecting SIP-based communications, including traffic inspection, encryption support, access control, network topology protection and call-routing policies. These functions help organizations reduce exposure to unauthorized communications traffic and manage the boundaries between trusted and external voice networks.

The solutions also provide monitoring and diagnostic capabilities to help telecommunications administrators investigate technical issues and maintain service quality.

Flexible Licensing and Deployment for Different Business Needs
M5 Technologies offers both software-based and hardware-based SBC architectures, allowing organizations to select solutions that correspond to their operational requirements.

Sentinel CS addresses virtual and cloud deployment requirements, while Sentinel 100 and Sentinel 400 provide dedicated hardware platforms for enterprise and hybrid telecommunications applications.

Maximum supported session capacities vary by product, configuration and licensing. Each concurrent SBC call requires the appropriate licensed capacity.

Businesses researching virtual SBC pricing, enterprise SBC solutions, cloud SBC provider infrastructure, SBC software licensing or carrier-grade SBC capabilities can contact M5 Technologies for technical consultations, product evaluations and commercial quotations.

Helping Organizations Modernize Without Replacing Everything
An important objective of the Mediatrix Sentinel portfolio is to help organizations adopt modern voice communications while preserving compatible existing infrastructure.

Rather than requiring a complete replacement of every telephone system, SBC technology can provide an essential connection between traditional communications equipment and modern IP-based platforms.

This approach can be especially valuable for businesses managing complex networks, multiple locations, specialized telephone equipment or gradual migrations toward cloud communications.

Through its Sentinel portfolio, M5 Technologies provides organizations with technologies designed to support secure voice connectivity, interoperability and communications continuity.
