Grandstream GRP2602W: Wireless 2‑Line Carrier‑Grade IP Phone with Wi‑Fi 6

The Grandstream GRP2602W is a wireless 2‑line essential IP phone from the carrier‑grade GRP series. It builds on the trusted GRP2602 feature set by adding integrated dual‑band (2.4 GHz and 5 GHz) Wi‑Fi 6 (802.11ax) , eliminating the need for a wired Ethernet connection. With support for 2 lines and 4 SIP accounts , it is ideal for on‑site and remote desktop workers, small‑to‑medium businesses, call centres, shared workspaces and anywhere that cabling is impractical.

At a glance, the GRP2602W’s core specifications include:

• 2 lines, 4 SIP accounts

• 2.4 inch (132×48) backlit graphical LCD display

• Dual 10/100 Mbps switched Ethernet ports

• Full‑duplex speakerphone with HD wideband audio

• 5‑way local audio conferencing

Flexible Wireless Connectivity

The GRP2602W is equipped with integrated dual‑band Wi‑Fi 6 (802.11ax) operating on 2.4 GHz and 5 GHz bands. This allows you to place the phone anywhere within coverage range – a temporary workstation, a reception desk without network ports, or a home office – simply connect to your existing wireless infrastructure.

When a wired connection is preferred, the phone also provides two 10/100 Mbps auto‑sensing Ethernet ports with integrated PoE support (powered via an 802.3af switch or injector). Both network interfaces can be used simultaneously, and if the Ethernet link is disconnected, the phone automatically notifies the user and offers a quick path to the Wi‑Fi settings page, keeping calls flowing.

Wi‑Fi security is covered by WPA/WPA2‑PSK and WPA/WPA2‑Enterprise (EAP‑FAST, EAP‑TLS, EAP‑TTLS, EAP‑PEAP, EAP‑MD5) , and the phone also supports 802.1X authentication on the wired interface for secure network access.

Crystal‑Clear Audio with AI Noise Reduction

The GRP2602W is equipped with Noise Shield Technology and AI noise reduction , which actively filters out background sounds (keyboard clicks, office chatter, air conditioning hum). This ensures both sides of the conversation hear clear, professional audio – even in busy or open‑plan environments.

The phone also provides HD wideband audio on the handset and full‑duplex speakerphone, supported by a comprehensive codec set: G.722 (HD), G.711µ/a, G.723.1, G.726‑32, G.729A/B, iLBC and OPUS . Advanced audio processing includes Voice Activity Detection (VAD), Comfort Noise Generation (CNG), Acoustic Echo Cancellation (AEC), Packet Loss Concealment (PLC), Adaptive Jitter Buffer (AJB) and Automatic Gain Control (AGC).

5‑way local audio conferencing is built in – easily bring multiple participants into a single discussion without an external conference bridge, making team collaboration simple and cost‑effective.

EHS Headset Support & Swappable Faceplate

For personal convenience, the GRP2602W includes an RJ‑9 headset jack with Electronic Hook Switch (EHS) support for Plantronics, Jabra and Sennheiser headsets – answer and end calls directly from your headset.

The phone also features a swappable faceplate , allowing businesses to customise the device with their own logo or branding – perfect for hotels, co‑working spaces or branded office environments.

Zero‑Touch Deployment via GDMS

The GRP2602W is fully supported by Grandstream Device Management System (GDMS) – a free cloud platform that delivers centralised zero‑touch provisioning, configuration, real‑time monitoring, firmware upgrades and troubleshooting for a single phone or across thousands of devices. GDMS also provides bank‑grade TLS encryption, two‑factor login authentication and two‑way certificate verification to protect your network.

For IT‑managed deployments, the phone also supports automated provisioning via TR‑069 and encrypted XML configuration files.

Enterprise‑Grade Security & High Availability

The GRP series includes carrier‑grade security features to provide enterprise‑level protection, including:

• Secure boot – prevents unauthorised firmware from loading

• Dual firmware images – safe, fail‑safe upgrades

• Encrypted data storage – protects sensitive configuration

• TLS and SRTP encryption – secures signalling and voice media

• 256‑bit AES encryption for configuration files
