Grandstream 2-Way SIP Intercom Speaker and Microphone

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.
