Product Features

Gigabit Network Performance for High-Speed Connectivity

The GRP2602G is equipped with dual 10/100/1000 Mbps Gigabit Ethernet ports, ensuring fast and stable network performance. This makes it suitable for environments where voice traffic and data applications share the same network infrastructure without compromising quality.

Integrated Power over Ethernet (PoE)

With built-in IEEE 802.3af PoE support, the phone can receive both power and network connectivity through a single Ethernet cable. This simplifies installation, reduces cable clutter, and lowers deployment costs in enterprise setups.

Multi-SIP Account Support for Flexible Communication

The device supports up to 4 SIP accounts with 2 physical lines, allowing users to manage multiple extensions, departments, or VoIP providers from one device. This enhances flexibility in shared workspaces and business environments.

HD Audio with Noise Shield Technology

The GRP2602G delivers HD voice quality on both handset and speakerphone with full-duplex communication. Noise Shield technology and advanced audio processing reduce background noise for clearer, more professional calls.

5-Way Audio Conferencing

Built-in 5-way conferencing enables users to conduct multi-party calls directly from the phone without requiring external conferencing systems, improving collaboration efficiency within teams.

Centralized Device Management with GDMS

The phone supports Grandstream Device Management System (GDMS), enabling zero-touch provisioning, remote configuration, firmware upgrades, and centralized monitoring for large-scale deployments.

Enterprise-Grade Security Architecture

Security features include secure boot, TLS encryption, SRTP voice encryption, dual firmware images, and encrypted configuration files, helping protect communications and prevent unauthorized access.

Professional Headset Integration

An RJ9 headset port with Electronic Hook Switch (EHS) support allows seamless integration with compatible wireless headsets, improving hands-free productivity in office environments.
