Grandstream GSC3510 SIP Paging Intercom Speaker PoE+ Wi-Fi Bluetooth 3 Mic | Wty

Grandstream GSC3510 — SIP Paging Intercom Speaker, PoE+, Wi-Fi, Bluetooth

The Grandstream GSC3510 is a ceiling-mount SIP paging speaker and intercom unit combining PoE+ power delivery, Wi-Fi, Bluetooth, and a 3-microphone array in a single device. Deploy on any SIP PBX to broadcast PA announcements, receive two-way intercom calls, or integrate with unified communications platforms. Backed by a 12-month Reboot IT warranty.

Key Benefits

• SIP paging over your existing PBX: Register directly to any SIP-compatible PBX — FreePBX, 3CX, Cisco UCM, hosted SIP — without proprietary paging hardware.
• PoE+ powered: 802.3at PoE+ delivers power over the Ethernet cable — ceiling mount with a single CAT6 run, no mains power outlet needed at the speaker location.
• Wi-Fi built-in: 802.11 b/g/n/ac Wi-Fi provides a wireless deployment path for retrofits where Ethernet runs aren’t available.
• 3-microphone array: Three directional microphones with noise cancellation enable clear two-way intercom conversations from anywhere in the room — not just directly below the device.
• Bluetooth 4.2: Stream audio from Bluetooth sources (phones, PCs) or use as a Bluetooth paging output for non-SIP audio scenarios.
• Full-duplex audio: Both parties can speak and hear simultaneously — no half-duplex push-to-talk limitations.

Performance in Use

The GSC3510 is designed for open-plan offices, warehouses, reception areas, and retail environments where PA paging and two-way intercom are needed without separate proprietary paging infrastructure. Register it as a SIP extension on your existing PBX and it appears as a standard endpoint — dial it to page, add it to a multicast paging group, or configure it as an auto-answer intercom station.

The 3-mic array means staff can respond to intercom calls from across a large room without approaching a wall-mounted handset. For larger sites, multiple GSC3510 units can be deployed in a multicast paging zone where a single PBX extension triggers all speakers simultaneously — a common configuration in manufacturing floors and logistics sites.

Frequently Asked Questions

Does the GSC3510 work with any SIP PBX?

Yes — it registers as a standard SIP endpoint and is compatible with any RFC 3261-compliant PBX including FreePBX, 3CX, Cisco UCM, and most hosted SIP providers.

Does it need PoE or can it use a power adapter?

The GSC3510 supports 802.3at PoE+ via RJ45 and also a DC 12V input for non-PoE deployments. A DC power adapter is not included.

Can it page multiple speakers at once?

Yes — the GSC3510 supports SIP multicast paging, allowing a single page to trigger all speakers in a configured group simultaneously. Set multicast addresses via the web UI or PBX.

Can I stream Bluetooth audio to it?

Yes — Bluetooth 4.2 allows audio streaming from paired smartphones, laptops, or tablets — useful as a secondary playback function outside of SIP paging use.

What shipping costs apply?

Shipping costs apply based on size and destination — rates are calculated at checkout.
