The GSC3510 supports a wide-range of peripherals including Bluetooth devices, built-in whitelist and blacklists to easily block unwanted calls, integrated dual-band WiFi and advanced acoustic echo cancellation. By pairing the GSC3510 with other Grandstream devices, including desktop and cordless IP phones as well as the GDS series of Facility Access products, users can easily sculpt a state-of-the-art security and voice intercom solution. Thanks to it’s modern industrial design and rich features, the GSC3510 is the ideal intercom speaker/microphone for any setting.

Secure, simple to use paging capabilities for mass announcements
The added security and intercom-paging capabilities of the GSC3510 SIP intercom, allows for quick and straight-forward mass announcements and the ability to configure desktop endpoints to quickly page through all GSC intercoms. For example, to page a specific doctor in a healthcare deployment, make announcements throughout event spaces, request more cashiers in a shop.

Two way intercom
The device can work as a two way intercom which allows for quick conversations when paging/calling specific GSC units within a communications network. For example, calling a classroom to request a student to be sent to a main-office.

Easy configuration with Grandstream devices
Grandstream’s proprietary Push-to-Talk capable devices can be configured to directly PTT through a specific or series of GSC3510 devices. The GSC3510, when paired with any of the Grandstream desktop and cordless IP phones, or any of the DGS series of door phones, offers a state-of-the-art security and voice intercom solution.

2-pin multi-purpose input
The GSC3510 also features 2-pin multi-purpose input that supports multitudes of peripherals including, a call-button or panic-button that would enable the GSC3510 to initiate a call to a predetermined endpoint, such as a security office phone or reception phone. When used with a call-button peripheral, the GSC can function as a security device to protect both in-network users and out-of-network users. Access through a facility can be controlled through an individual initiating a call through the GSC3510, or a panic-button can connect a user with security staff in the case of an emergency.

Accessible for easy-way mobility
When deployed in senior-care or healthcare industries, the GSC3510 can provide an easy way for mobility-impaired users to connect with nursing and healthcare staff.
