Who is Ingate Systems?

Ingate Systems is a telecommunications and networking vendor that develops enterprise-focused Session Border Controller and SIP-based solutions for secure real-time communications over IP networks.

Enterprise Session Border Controllers (SBCs) for Session Initiation Protocol (SIP) trunking and unified communications security (networking/security)
SIP-based solutions for real-time voice, video, and messaging over IP networks (unified communications)
Tools for secure traversal of firewalls and Network Address Translation (NAT) in SIP environments (networking)
Support for SIP trunking deployments with service providers and enterprise PBXs (telecom infrastructure)
Products and guidance for migration from legacy telephony to IP-based communications (voice over IP)

More About Ingate Systems

Ingate Systems focuses on enabling SIP-based real-time communications for enterprises and service providers through Session Border Controllers (SBCs) and related SIP infrastructure products. Its offerings are designed for deployment at network edges where enterprises interconnect with service providers, or where different IP communications domains meet. In these locations, SBCs handle signaling control, media handling, and security enforcement for SIP-based voice, video, and messaging sessions.

In enterprise environments, Ingate Systems products are used to support SIP trunking, unified communications, and IP-based contact center architectures. SBCs from Ingate Systems (Session Border Controller) are typically deployed between an enterprise IP-PBX or unified communications platform and an external SIP trunk or carrier network (telecom infrastructure). They provide functions such as SIP normalization, topology hiding, encryption handling, and interoperability between different SIP implementations. This placement allows enterprises to connect internal communications platforms to external networks while maintaining control over signaling and media flows.

Ingate Systems offerings also address firewall and NAT traversal for SIP. Traditional firewalls are not designed to understand SIP signaling and dynamic media port allocations, which can block or degrade real-time communications traffic. Ingate Systems products integrate SIP-aware capabilities that interpret SIP messages, open required media paths, and close them when sessions end. This approach allows enterprises to maintain existing security postures while enabling voice and video over IP. The company’s solutions generally support standard SIP protocols and related technologies defined by bodies such as the Internet Engineering Task Force (IETF).

From a technology perspective, Ingate Systems focuses on SIP (Session Initiation Protocol) and related real-time transport protocols. Its offerings are typically positioned alongside IP-PBX platforms, unified communications systems, and carrier SIP trunking services. In many deployments, Ingate Systems SBCs coexist with existing firewall and router infrastructure, adding application-layer control for SIP sessions on top of IP-layer security and routing. This allows enterprises to keep network segmentation, Quality of Service (QoS), and routing policies in their current infrastructure while delegating SIP-specific control to the SBC.

Within an enterprise IT directory or marketplace taxonomy, Ingate Systems maps primarily to categories such as Session Border Controllers (networking/security), SIP trunking enablement (telecom infrastructure), and unified communications connectivity (collaboration). Its products are relevant for organizations planning migrations from legacy TDM or ISDN trunks to SIP trunks, or for those standardizing on SIP-based unified communications. The company’s focus on SIP standards and enterprise deployment models places its offerings in the domain of real-time communications infrastructure rather than general-purpose networking or cloud services.
