More product details
The Grandstream GAC2500 is an Android-based conference phone designed for meeting rooms and huddle spaces where flexibility and app integration matter. It runs Android 4.4 and gives you access to the Google Play Store, so you can install third-party collaboration apps like Zoom, Microsoft Teams, or your own custom UC client directly on the device. This makes it a good fit for businesses that want a single device for both SIP telephony and softphone-style conferencing, without needing a separate PC or tablet in the room.
It supports up to 6 SIP accounts and includes a built-in 7-way audio conference bridge, which is practical for small to mid-sized teams that run frequent internal calls or client meetings. The 4.3-inch touchscreen and Bluetooth support for headsets or mobile syncing add convenience, but the device is best suited for rooms where participants sit within about 12 feet of the unit—its three cardioid microphones cover 360 degrees but won't fill a large boardroom. For bigger spaces, you might need to daisy-chain two units or look at a ceiling-mic array system.
On the networking side, the GAC2500 has a Gigabit port with PoE+ support, so it can be powered over Ethernet without a separate power brick—handy for clean desk setups. It also includes TLS and SRTP encryption, which is important for Canadian businesses handling sensitive client data. However, note that it runs an older Android version (4.4), so some newer apps may not be compatible or may lack security updates. If your organization requires the latest Android security patches or needs to run modern UC apps that demand a newer OS, this device may feel limited. It's a solid choice for a dedicated conference room phone that doubles as an Android endpoint, but not for environments that need cutting-edge app support or very large room coverage.
