Grandstream • SKU GAC2500
A legacy Android conference phone with six SIP accounts, seven-way voice conferencing, a 4.3-inch touchscreen, Wi-Fi, Bluetooth, Gigabit Ethernet and PoE.

The GAC2500 combines SIP conferencing, full HD audio, dual Gigabit networking, Wi-Fi and Bluetooth in an Android 4.4-era conference phone. It can daisy-chain with a second GAC2500 for supported room designs, but its legacy software and app ecosystem require careful security and service checks.
Quick answer: Choose the GAC2500 only for a confirmed legacy or replacement requirement. Do not rely on old Google Play, Skype or Hangouts claims for a current deployment; verify firmware, security, app/service and SIP-platform support first.
Use six SIP accounts and the built-in seven-way conference bridge in a compatible system.
Connect through Gigabit Ethernet, Wi-Fi or supported Bluetooth workflows.
Manage calls and supported functions from the 4.3-inch capacitive display.
A quick fit check for Australian businesses comparing equipment for users, rooms, sites or wider projects.
