Enterprise SBC solutions for every voice environment
ProSBC addresses the specific voice infrastructure challenges enterprises face across different operational environments.
Enterprise SIP trunking
Large organizations connecting IP PBX systems through multiple operators for toll-free, inbound DID, and international calling rely on an SBC for interoperability, application protection, outbound call routing, and load balancing. ProSBC’s B2BUA architecture and SIP header manipulation engine normalize signaling across carriers and platforms.
Contact centers
Contact centers and BPOs migrating to cloud platforms such as Genesys, Five9, or NICE need a Bring Your Own Carrier (BYOC) SBC to manage SIP trunking, secure media streams, and maintain call quality between their carrier connections and the cloud platform. ProSBC facilitates and protects access to hosted contact center, conferencing, and unified communications applications.
Microsoft Teams Direct Routing
Enterprises deploying Microsoft Teams as their phone system can use ProSBC to connect Teams to PSTN carriers via Direct Routing. ProSBC supports Teams Direct Routing deployments and has been successfully deployed in Teams DR environments, enabling secure PSTN voice connectivity alongside the Teams collaboration platform.
Branch offices and distributed sites
Organizations with multiple locations can extend SBC routing logic and traffic management to branch offices and subscriber premises for local traffic handling and early filtering, reducing the load on centralized infrastructure while maintaining consistent security and call quality policies across all sites.

Frequently Asked Questions
How does licensing scale? Can we start small and expand as traffic grows?
Yes. TelcoBridges ProSBC offers flexible, pay-as-you-go licensing that scales with business needs. Through simple license upgrades, enterprises can start with a smaller deployment and easily expand capacity from 500 to 60,000 concurrent sessions.
What is the cost advantage versus large SBC vendors?
TelcoBridges ProSBC provides a clear cost advantage compared with traditional SBC vendors. Our flexible, pay-as-you-go licensing reduces upfront capital expenditures and eliminates the need for costly, fixed hardware. Enterprises can scale capacity as needed, only paying for what they use, while still accessing carrier-grade performance, security, and advanced features, making it a more cost-effective solution for growing networks and unified communications environments.
Can ProSBC scale to meet our traffic peaks?
Yes. ProSBC is designed to scale with network traffic, allowing enterprises to handle traffic peaks without downtime or performance degradation.
How does ProSBC integrate with fraud prevention and compliance requirements?
ProSBC integrates directly with external systems to help enterprises enforce fraud prevention and meet compliance requirements. With a powerful, flexible scripting engine and Application Programming Interface (API), ProSBC can interact with fraud detection platforms, STIR/SHAKEN authentication services, and other regulatory tools in real time. This enables enterprises to block suspicious calls, verify caller identity, and maintain regulatory compliance.
Can enterprises offload monitoring and management?
Yes. With ProSBC Managed Services, TelcoBridges allows enterprises to offload the day-to-day monitoring, management, and maintenance of their Session Border Controllers. Our technical experts handle setup, configuration, ongoing monitoring, and troubleshooting, giving teams peace of mind, reducing operational burden, and ensuring voice networks run reliably and efficiently.
How easy is troubleshooting with ProSBC?
Troubleshooting with ProSBC is designed to be straightforward and efficient. ProSBC includes integrated analytics, detailed call logs, and real-time monitoring tools, allowing enterprises to quickly identify and resolve issues. For additional support, TelcoBridges’ technical team is available through ProSBC Managed Services or as an add-on, providing expert guidance to fix problems as soon as they arise and minimize downtime.
What deployment models does ProSBC support?
ProSBC runs on VMware, KVM/Proxmox, as a VNF on uCPE, on AWS, Microsoft Azure, and bare-metal servers. All deployments can be on customer premises for data protection and compliance requirements. Enterprises that prefer not to manage their own SBC can use ProSBC Managed Service, where TelcoBridges handles setup, integration, testing, and ongoing monitoring on the customer’s chosen platform or hosted by TelcoBridges.
What is the difference between an enterprise SBC and a carrier-grade SBC?
A carrier-grade SBC is built for the performance, reliability, and scale demands of telecommunications service providers, handling tens of thousands of concurrent sessions with high availability. An enterprise SBC applies that same technology to protect and manage voice traffic within a business network. ProSBC is carrier-grade by design, scaling from 500 to 60,000 concurrent sessions, which means enterprise deployments benefit from the same architecture that service providers rely on without needing a separate product line.
How is ProSBC priced for enterprise deployments?
ProSBC uses an annual subscription model starting from $1.25 per session per server per year, replacing traditional hardware capital expenditures with predictable operating expenses. Managed Service is available starting from approximately $500 per month, including 1+1 High Availability, 24×7 support, and full setup and monitoring.
