Grandstream Networks, the award-winning supplier of unified communications, has  has recently released, the GSC Series of SIP intercom solutions which include the GSC3510, SIP intercom speaker/microphone, and the GSC3505, 1-way public address SIP speaker.

These SIP Intercom solutions bring powerful voice intercom and extended security to any deployment scenario including offices, hospitals, hotels, residential buildings, and educational institutions.

See typical examples of how the GSC SIP Intercom series benefits major industries and environments, below:


Safeguard and improve office communication by deploying the Grandsteam GSC3505 1-way public SIP address speaker for important announcements. Ideal for large, multi-floor offices, this system can be paired with Grandstream’s desktop and cordless IP phones as well as the GDS series of facility access products, users can create a seamless security solution to screen for and interact with employees, visitors, and guests.



In a hospitality environment such as a hotel, restaurant, casino, etc., you will want to ensure that it is equipped with a clear and concise intercom system to provide an enhanced communication system for both staff and guests. By eliminating expensive wiring costs, important communication can be delivered faster and more reliable thanks to the integrated dual-band 802.11 a/c/g/n WiFi. The GSC3505 public address SIP speaker can be used for both emergency and non-emergency announcements, background music, and more. Additionally, this system can pair with Grandstream’s desktop IP phones and cordless IP phones as well as the GDS series of Facility Access products that users can create a customized facility management solution.


Deploying a GSC3505 public address SIP speaker throughout any large public space in a school system will allow for quick and reliable mass announcements. This type of solution could be deployed into hallways, cafeterias, and libraries, for use in period/class changes, emergencies, general announcements and more. This 1-way SIP speaker is also equipped with an HD acoustic chamber which can help to eliminate echoes that often occur in school hallways and large classrooms.

The Granstream GSC3510  SIP Intercom Speaker and Microphone is ideal for individual classrooms and main offices,  It can be used for two-way communication. This speaker makes it possible for teachers and students to quickly interact with the main office without much intrusion from teaching. The GSC3510 includes 3 directional microphones with MMAD so a teacher can be standing anywhere within the classroom and can clearly be heard by the receiving end. Traditional intercom systems can become expensive due to the wiring of individual systems in each classroom, which makes this solution more affordable and reliable due to the integrated dual-band WiFi.


In a logistics environment, being able to communicate hands-free is key. In large facilities, it can be hard to deliver mass announcements relating to closing periods, incoming deliveries or emergencies. The GSC3505 public address SIP speaker enables employees to continue their work without being hindered by a communication device such as a desktop phone. Grandstream’s 1-way public address SIP speaker is equipped with an acoustic chamber to eliminate echoes throughout any environment and will provide a reliable source of instant communication to all workers. Paired with the WP820 cordless IP phone, staff leads can easily communicate through the speaker by using the push-to-talk functionality.


The GSC3505 public address SIP speaker is ideal for large medical facilities such as a hospital as this SIP speaker allows for crystal clear HD audio announcements. Deploy this audio communication system throughout the entire facility to ensure that any emergency announcement such as a lockdown, incoming ER patients, or doctor will broadcast without question. The GSC3505 SIP and multicast paging feature is ideal for a hospital scenario where certain ‘priority groups’ can be set up and users can assign other devices to these groups. For example, general announcements might have a lower priority over emergency pages. This way, when a general announcement is going over a GSC3505 from a reception desk phone such as a GXP2130 HD IP Phone, an emergency page from a doctor’s WP820 WiFi phone can cut in and take priority through the GSC.  

The GSC3510 SIP speaker/microphone would be most useful for individual patient hospital rooms, or at a nursing facility for a reliable two-way communication system. Both patients and staff can use this solution to narrow response time and increase safety, especially when mobility may be an issue. In this scenario utilising the devices’ two-pin peripheral port can hook up to an emergency button that patients can hit to auto-dial nursing stations. Additionally, this could be paired with Grandstream’s GDS series of Facility Access Systems to communicate with incoming guests, patients, and employees outside of normal facility hours.
