More About Grandstream Networks
Grandstream Networks focuses on IP communications and networking products used by enterprises, SMBs, service providers, and institutional customers that adopt SIP-based architectures for voice, video, and data. Its portfolio spans unified communications (UC), collaboration, networking, and surveillance categories, with an emphasis on standards-based interoperability in multi-vendor environments.
In unified communications, Grandstream provides IP PBX systems and VoIP gateways (unified communications) built around Session Initiation Protocol (SIP) and standard telephony interfaces, enabling IP-based call control, extension management, and connectivity to PSTN or ITSP services. These platforms are typically deployed as on-premises (on-prem) appliances within branch offices, campus environments, and hosted provider infrastructures. They integrate with SIP trunking, support various codecs such as G.711 and G.729, and expose web-based administration for configuration and monitoring.
Grandstream’s IP phones, video phones, and conferencing endpoints (communications endpoints) are used on enterprise desks, in conference rooms, and in shared spaces. These endpoints typically support SIP registration to third-party IP PBX and hosted UC platforms, PoE-based deployment, and features such as BLF, multi-line accounts, and secure signaling and media via Transport Layer Security (TLS) and SRTP, depending on model and configuration. Video-capable endpoints extend this model to include integrated cameras, displays, and codecs for point-to-point and multi-party video sessions.
The company also offers IP video conferencing systems (collaboration) designed for meeting rooms and distributed teams. These systems usually combine cameras, speakerphones, and codec units that connect to SIP-based infrastructures, cloud conferencing platforms, or H.323-compatible systems if supported. They are positioned for organizations that prefer standards-based room systems over proprietary conferencing ecosystems, and they can be integrated into broader UC deployments for voice, video, and content sharing.
In networking, Grandstream provides wireless access points, routers, and related appliances (enterprise networking) that support Wi-Fi, routing, and security features appropriate for branch and campus environments. These products are generally managed via web interfaces or centralized controllers, and are used to build IP infrastructure that also carries real-time voice and video traffic. Quality of Service (QoS) capabilities are typically used to prioritize SIP and Real-time Transport Protocol (RTP) traffic across wired and wireless segments, supporting end-to-end UC performance.
Grandstream’s IP surveillance cameras and video management offerings (video surveillance) extend the portfolio into physical security. These devices support IP video streaming, commonly using protocols such as RTSP and ONVIF for integration with third-party video management systems. They are deployed in facilities that require both communication and surveillance capabilities over a converged IP network, allowing customers to maintain a single infrastructure for voice, data, and video.
Across these solution areas, Grandstream positions its offerings for organizations seeking standards-based IP communications, with SIP, RTP, RTSP, and ONVIF as central protocols. In enterprise directories, its products map to unified communications platforms, SIP endpoints, IP networking hardware, and IP video surveillance systems that are deployable in on-prem, hybrid, or service provider-managed environments.
