Grandstream GS-GAC2500 3-Way Calling Conference Phone

Grandstream GAC2500 – Android Conference Phone with 3‑Way Calling

The Grandstream GS‑GAC2500 is a powerful Android‑based conference phone that brings crystal‑clear audio and smart collaboration to huddle rooms, executive offices, and small meeting spaces. Unlike basic speakerphones, the GAC2500 features a 7‑inch capacitive touchscreen, HD audio with dual‑band Wi‑Fi and Bluetooth, and support for 3‑way conferencing natively. It runs the Android operating system, allowing you to install popular UC apps like Microsoft Teams, Zoom, Google Meet, and Skype for Business directly on the device. With its full‑duplex speakerphone and advanced echo cancellation, every participant’s voice comes through naturally – even in smaller rooms.

How It Works

The GAC2500 connects to your network via Gigabit Ethernet (with PoE) or dual‑band Wi‑Fi. Its 7” touchscreen lets you control calls, access contacts, and launch video conferencing apps. The device supports up to 3 simultaneous calls (3‑way conferencing) natively, and you can easily merge calls, transfer, or host a multi‑party conversation. The Android OS means you can also run third‑party softphones and collaboration tools. The built‑in Bluetooth allows you to pair a wireless headset for private listening or use the device as a Bluetooth speakerphone. For teams looking to equip a small meeting room, this conference phone can be the central hub. To extend the range or allow private participation, consider using a wireless headset – browse our selection at FindHeadsets for models that pair seamlessly via Bluetooth.

Compatibility & Design

The Grandstream GAC2500 works with any SIP‑based VoIP system, as well as with popular UC platforms through Android apps. It supports 6 SIP accounts, 3 lines, and up to 3 concurrent calls. Audio features include full‑duplex speakerphone, acoustic echo cancellation, and noise suppression. The device has dual‑band Wi‑Fi (2.4GHz/5GHz), Bluetooth 4.0, Gigabit Ethernet with PoE, and a USB port for peripherals. The 7” capacitive touchscreen (1024×600) provides a crisp interface for call management, settings, and app navigation. The unit is designed for desktop or table placement, with an angled design for easy viewing. It includes a built‑in omnidirectional microphone array that covers up to 10 feet, and the speaker can handle medium-sized rooms.

Why Choose This Product

The GAC2500 stands out because it’s not just a conference speaker – it’s a full Android device. You can install Zoom, Teams, or your own SIP client directly on the phone, eliminating the need for a separate PC in the conference room. The 7” touchscreen makes joining meetings as easy as tapping an icon. The built‑in 3‑way mixing is perfect for small calls without a bridge. The audio quality is excellent for its class, with clear full‑duplex sound and effective echo cancellation. For businesses already using Grandstream IP PBXs, the GAC2500 integrates seamlessly. The flexibility of PoE or Wi‑Fi installation means you can place it anywhere without a dedicated Ethernet drop. Compared to basic analogue conference phones, this device is a giant leap forward.
