====

The Grandstream GAC2570 is a conference phone that does not need to stay tethered to a wall socket or a network cable. A 3300 mAh battery gives up to 4 hours of talk time, and dual-band Wi-Fi 6 plus Bluetooth 5.0 handle the connections. On the table, 12 microphones capture up to 12 attendees within 5 m, and the unit hosts conferences of up to 12 parties, a good match for boardrooms and mid-size meeting rooms.

Grandstream GAC2570 audio and pickup

Grandstream uses an array of 12 omnidirectional microphones with beamforming, so pickup follows whoever is speaking and room echo drops. The speaker is full duplex, so neither side gets cut off when both talk at once.

• 12 microphones, 5 m pickup range.
• 10W speaker, 100-20,000 Hz, up to 83 dBA at 1 m.
• Echo cancellation (AEC), noise suppression (ANS) and Noise Shield.
• Full-band audio with G.722, G.722.1c and Opus.

Wider reach with GMD1208 microphones

For a long boardroom table, add up to two GMD1208 wireless microphones and pickup extends to 20 m. Pairing takes seconds: enable Wireless MIC in settings, hold the mic about 10 cm from the phone and press its pair button.

A meeting that moves with you

Battery power and Wi-Fi make the GAC2570 portable. Start a call at your desk, walk it into the meeting room, and the conference keeps going. The unit can also act as a Wi-Fi hotspot when needed.

Screen and ports

The 7-inch 1280x800 touchscreen shows participants and call controls clearly. Around the back you get HDMI IN for presentation sharing through GVC32xx systems, line-out for external speakers, Micro-USB for use as a PC speakerphone and a Kensington lock slot. Calls can be recorded locally or on the server.

Where it works in Saudi Arabia

• Boardrooms in corporate offices and towers across Riyadh.
• Shared meeting rooms that several departments book and move between.
• Regular calls with branches in Jeddah, Dammam and Makkah.
• Training halls where the speaker stands far from the table.

Compatibility and setup

The GAC2570 registers to SIP PBXs, including Grandstream UCM systems, and supports 2 SIP accounts. It draws power from an 802.3at Class 4 PoE+ switch, and a PoE injector is in the box for sites without one. Mass provisioning uses an AES-encrypted XML file, and OpenVPN is supported for secure remote links.

GAC2570 or GAC2500?

The GAC2570 wins on microphones (12 vs 3), pickup range (5 m vs 12 ft), screen size (7 vs 4.3 inches) and conference size (12 vs 7 parties), and adds Android 10, Wi-Fi 6, a battery, HDMI IN and GMD1208 support. The GAC2500 supports 6 SIP accounts against 2 and daisy-chains to a second unit over RJ48. If you need several SIP accounts on one phone, the GAC2500 fits better; for most meeting rooms the GAC2570 is the stronger choice.
