GRP2601(L/LP/LW)

In a complete network deployment, the GRP2601L/LP/LW IP phones serve as the core endpoints for business communication. These phones connect directly to a local network switch, which manages voice traffic and builds the local network framework.

Through this switch, the GRP2601L/LP/ LW terminals communicate internally with the UCM IP PBX server for centralized call control. To enable external connectivity, the switch links the entire voice subsystem to an edge router, which serves as the secure gateway to the internet.

This topology allows the GRP2601L/LP/ LW phones to register seamlessly with both on-premise and cloud servers, unlocking reliable local and external calling capabilities.

The series is fully compatible with the GS EXT app, serving as a highly efficient alternative to a physical expansion module and transforming your smartphone into a customizable control panel.

With a few simple taps, you can effortlessly configure speed dials, BLF (Busy Lamp Field), Call Pickup, and other programmable functions without purchasing any extra hardware.

This innovative digital solution makes our IP phone series perfect for remote workers and budget-conscious professionals who want to expand their call-handling capabilities cost-effectively.

The Grandstream GRP Click2Dial browser extension enables seamless integration between your computer and the IP phone series.

Without interrupting your active calls, this powerful utility allows you to share screens, transfer files, and add on-screen notes directly from your web browser.

By extending the capabilities of your desktop phone into your digital workspace, the extension bridges the gap between hardware and software to significantly optimize daily team collaboration. 

Crystal-Clear and Stable Communication

This series combines traditional audio filtering with advanced AI noise cancellation to deliver distraction-free conversations. They can filter out ambient noises like the humming of an air conditioner but also identify and eliminate sudden environmental disturbances, such as mouse clicks and keystrokes.

To guarantee performance over unstable networks, the series features our self developed GS-FEC technology. By successfully resisting up to a 70% audio packet loss rate, it maintains steady, reliable voice transmission so that every call remains clear and professional. 

Robust SDK Integration

This series features a comprehensive SDK designed to unlock flexible customization capabilities.

Whether you are integrating a CRM, architecting custom call center solutions, or developing entirely new applications, our SDK delivers the necessary APIs, tools, and sample code to streamline your deployment.

With a completely open architecture and zero restrictions, it offers developers total flexibility—making it the ideal choice for system integrators, solution providers, and enterprises with specialized workflow requirements.

Advanced WireGuard Support

The GRP2601L/LP/LW IP phones integrate natively with WireGuard to deliver a streamlined, lightweight framework that is faster than OpenVPN and less complex than IPsec.

This powerful integration creates a dedicated, high-speed encrypted tunnel, ensuring every remote call is shielded by cutting-edge, modern cryptography.
