Description
For businesses that need more than a basic speakerphone, the Grandstream GAC2500 Android Enterprise Conference Phone delivers powerful 7-way conferencing, crystal-clear HD audio, and the familiar Android 4.4 interface so your team can connect, collaborate, and even run productivity apps right from the conference table. With a 4.3" touchscreen, built-in Wi-Fi for wireless placement, and Bluetooth for easy mobile syncing, it gives IT directors and facilities managers the flexibility they want without complicated setups.
The Telecom Spot Take
Our customers tell us the GAC2500 changes how they run meetings. The built-in 7-way conference bridge means you can host large calls without extra bridges or services. Three cardioid microphones pick up voices clearly from 12 feet away in every direction, while the full-duplex HD speaker delivers rich sound up to 86 dB. Android 4.4 plus Google Play Store access lets you add apps like calendar or messaging tools, and daisy-chain support scales for bigger rooms. Paired with Gigabit PoE and strong TLS/SRTP security, it’s a reliable, future-ready choice that keeps your meetings productive and your network simple.
