TelcoBridges

What TelcoBridges does

TelcoBridges Inc. designs, manufactures, and supports voice network infrastructure for service providers and enterprises. Founded in 2002 and headquartered in Boucherville, Canada, the company operates two product families: Tmedia hardware media and signaling gateways (including the TMG800, TMG3200, and TMG7800 models, plus the Tsig SS7-to-SIGTRAN signaling gateways), and ProSBC, a software-based Session Border Controller (SBC) built on B2BUA architecture with a programmable Ruby routing engine. ProSBC scales to 60,000 concurrent sessions and 350,000 SIP endpoint registrations per server, deploys on VMware, KVM/Proxmox, AWS, Azure, or bare metal, and supports per-call STIR/SHAKEN attestation, CNAM lookup, fraud detection, hardware-assisted transcoding, geo-redundant active/standby failover, and (as of 2025) a free MCP (Model Context Protocol) server that exposes configuration and routing management to MCP-compatible large language models under explicit user approval with audit logging.

The company serves internet service providers (ISPs), managed service providers (MSPs), contact centers, carriers and CLECs, enterprises with Microsoft Teams or UC voice connectivity needs, and CPaaS providers migrating off per-minute vendors like Twilio. The customer base spans 300+ service providers, with named deployments at Nokia, Frontier, Ziply Fiber, Atento, UnitedCloud, Paratus, Vivaro, Infomedia, and Inovo, and the company states that Tmedia hardware runs in carrier core networks across 110+ countries.

Revenue is generated through a mix of transparent subscription software licensing for ProSBC ($1.25/session/year, with a $0.75/session/year Microsoft Teams Direct Routing add-on), hardware sales of Tmedia and Tsig gateways, a fully managed ProSBC service in which TelcoBridges handles installation, security hardening, upgrades, and 24x7 monitoring, monitoring-as-a-service subscriptions, and support and training contracts. Distribution is hybrid: self-serve product-led growth via a free permanent 3-session ProSBC Lab and 30-day 500-concurrent-session trial combined with direct enterprise sales, plus a Genesys AppFoundry marketplace listing. The company is privately held, has operated without external funding for over 20 years, and reports itself as profitable, with 100% of R&D conducted in-house in Canada.

Core offering

TelcoBridges designs, develops, and sells carrier-grade voice network infrastructure headlined by ProSBC — a software Session Border Controller built on B2BUA architecture with a programmable Ruby routing engine — together with Tmedia hardware media gateways and Tsig signaling gateways. ProSBC secures, routes, normalizes, and manages SIP-based voice traffic for ISPs, MSPs, contact centers, carriers, and enterprises, with add-ons for Microsoft Teams Direct Routing, hardware-assisted transcoding, and 24x7 monitoring. The company also offers a fully managed ProSBC deployment option and direct L3 engineer support.

Product overview

TelcoBridges offers a unified portfolio of VoIP infrastructure products comprising two main families: ProSBC (software Session Border Controller) and Tmedia/Tsig (media and signaling gateways). ProSBC is the core software SBC platform with add-on modules including ProSBC Lab (free testing environment), ProSBC Managed Service (fully managed option), ProSBC for Microsoft Teams (Direct Routing), Monitoring as a Service, and Transcoding. The Tmedia media gateway line includes the TMG800 (256 channels), TMG3200 (2,016 channels), and TMG7800 (32,768 channels). Tsig signaling gateways (TSG800, TSG3200) provide SIGTRAN migration capabilities. Supporting solutions include fraud detection, STIR/SHAKEN attestation, SBC APIs with Ruby routing scripts, and the MCP server for AI-driven natural language configuration.

Broad incumbents

• Oracle (Acme Packet): Oracle's Acme Packet SBC portfolio is the dominant carrier-grade SBC franchise for large operators and enterprises — a broad incumbent that competes with ProSBC across the largest tier-1 deployments.
• Avaya: Avaya offers SBC functionality integrated with its Aura UC platform and Oceana contact-center solutions — a broad incumbent that competes with ProSBC for enterprise SBC and Teams Direct Routing workloads.
• Twilio: Twilio is a leading CPaaS provider whose per-minute voice pricing TelcoBridges explicitly targets for displacement; a broad incumbent that competes indirectly via its Elastic SIP Trunking and Voice APIs.
• Cisco: Cisco sells the Unified Border Element (CUBE) SBC as part of its broader UC, collaboration, and networking portfolio — a broad incumbent competing with ProSBC especially in enterprise and Microsoft Teams Direct Routing deals.

Direct peers

• Ribbon Communications: Ribbon Communications (formerly Sonus/GenBand) sells carrier-grade SBCs (SBC Core, SBC 5400/7000) and media gateways directly competing with ProSBC and Tmedia across service-provider and enterprise segments.
• Sansay: Sansay provides software SBCs, session management, and VoIP infrastructure for carriers and wholesale providers — a direct peer to ProSBC with comparable carrier-class feature set and pricing model.
• Sangoma Technologies: Sangoma offers SBCs, VoIP gateways, and UCaaS/PBX solutions to SMBs and service providers — a direct peer to TelcoBridges across SBC and media gateway product lines, with overlapping carrier-customer base.
• Ingate Systems: Ingate Systems specializes in SIP-aware firewalls and enterprise SBCs for Microsoft Teams Direct Routing and SIP trunking — a direct peer in the SMB/enterprise SBC niche where ProSBC also competes.
• AudioCodes: AudioCodes is a leading vendor of Session Border Controllers, VoIP gateways, and SIP telephony infrastructure for service providers and enterprises — the closest direct competitor to TelcoBridges ProSBC and Tmedia.

Emerging players

• Kamailio (open source): Kamailio is the leading open-source SIP proxy/SBC, frequently cited by TelcoBridges as the alternative customers are escaping due to operational complexity — an emerging/dissenting alternative in the same SBC category.
