====

The Grandstream GRP2601W is a 2-line desk IP phone with 2 SIP accounts that joins the network wirelessly over 2.4 GHz Wi-Fi 6. All it needs is a power socket and Wi-Fi coverage, so it can go into an office added after the cabling was done, a small meeting room, or a building where nobody wants to chase new cable through the walls. The power adapter comes in the box.

When Wi-Fi beats a cable

A new desk in a corner the cabling never reached, a storeroom turned into a supervisor's office, a temporary site office on a project: in each case, pulling a new network cable is expensive or simply not possible. The GRP2601W handles it. Turn on Wi-Fi from the phone menu (Settings, then Wi-Fi settings), pick the network, enter the password and the phone registers to your PBX. If a cable turns up later, the two Ethernet ports are there too.

Getting the wireless side right

The phone uses the 2.4 GHz band only, so make sure your access point broadcasts on 2.4 GHz where the phone will sit. For steady calls, keep the signal strong at the desk and enable QoS on the network; the phone supports 802.1p and DiffServ priority tagging. If your network splits the bands into two names, pick the 2.4 GHz SSID during setup.

Calls and audio

Hold, transfer, forward, call park, call pickup, 5-way conferencing and a phonebook of up to 2,000 entries. Audio runs on G.722 and Opus codecs with Noise Shield and AI noise reduction, and an RJ9 jack takes an EHS-compatible headset.

Security and remote management

Secure boot, dual firmware images and encrypted storage, plus TLS 1.3 and SRTP call encryption. You can provision the phone remotely through GDMS, TR-069 or encrypted XML files, useful when the handset sits in a building far from the IT team.

Good places for the GRP2601W

• Desks added after the network was installed.
• Temporary and portable site offices on projects.
• Older buildings where new cabling is hard to run.
• Supervisor offices inside warehouses and workshops.

PBX compatibility

It speaks standard SIP, so it works with Grandstream UCM systems, Yeastar PBXs and any other SIP platform, on the local network or over the internet.

GRP2601W vs GRP2601 vs GRP2601P

All three share the screen, two lines and two SIP accounts. The GRP2601W is the only one with Wi-Fi. The GRP2601 is wired only and includes an adapter. The GRP2601P is wired and powered by a PoE switch, with no adapter. The GRP2601W itself does not support PoE.

Frequently Asked Questions

Does the GRP2601W support 5 GHz Wi-Fi?

No. It is single-band 2.4 GHz Wi-Fi 6 (802.11b/g/n/ax).

Is it PoE powered?

No. PoE is on the GRP2601P only; the GRP2601W runs on its included 5 V / 600 mA adapter.

Can I still use a network cable?

Yes. The datasheet lists dual 10/100 Mbps Ethernet ports, so you can use cable or Wi-Fi.
