New Netbell IP paging solution leverages existing network infrastructure to reduce deployment costs
WINSTON-SALEM, NC, January 21, 2026 /24-7PressRelease/ -- Linortek, a Winston-Salem-based IoT solutions provider, has launched the Netbell IP Paging System, a network-based communication platform designed for schools, manufacturing facilities, warehouses, government and other commercial buildings.
The system utilizes Power over Ethernet (PoE) to deliver both power and audio through standard network cabling, eliminating the need for separate amplifiers and dedicated speaker wire runs typical of traditional public address systems.
The company developed the system in response to customer feedback about complexity and support challenges with legacy paging systems from established manufacturers. According to Linortek, many facilities struggle with systems that use multiple modules for different functions, require professional contractors for installation, and become difficult to modify or troubleshoot over time. The company reports that site visits revealed installations where facility staff could not determine system architecture or make changes without expensive manufacturer support services.
"The feedback we've received from customers centers on two main points: installation complexity and total cost of ownership," Liyu Nalven, President of Linortek said. "By using existing network infrastructure, facilities can deploy the system using their own IT staff rather than specialized AV contractors."
Technical Architecture
The Netbell system is available in two protocol variants. The IP speaker line uses Linortek's proprietary network audio protocol and is managed through a desktop configuration tool. The SIP speaker line, announced as part of this launch, implements the Session Initiation Protocol (SIP 2.0/RFC 3261), allowing direct integration with standards-compliant VoIP phone systems and other SIP-enabled devices.
Both product lines support unicast, multicast, and broadcast network protocols. The multicast implementation allows a single audio source to reach multiple speakers simultaneously without requiring individual network communication to each endpoint, which the company states can reduce VoIP system licensing requirements.
Hardware options include horn speakers rated at 30 watts for industrial environments, wall-mounted speakers at 20 watts for corridors, and ceiling-mounted speakers at 30 watts for office spaces. All models operate on 802.3at PoE power standards.
System Capabilities
The platform supports multiple use cases beyond basic paging. The Netbell-NTG-B controller module enables scheduling of up to 500 automated events through a web interface, which facilities can use for shift changes, break bells, emergency notifications, or routine announcements. The system can also integrate with building systems such as fire alarms and security panels through digital input connections or RESTful API.
For VoIP integration, SIP speakers register directly as extensions on compatible phone systems, while IP speakers require the AU-711-SIP gateway device. Additional hardware modules include IP-based microphone call stations with zone control capabilities, two-way intercom terminals for entrance points, and IP call boxes for distributed announcement stations.
The system operates on local area networks and does not require internet connectivity or cloud services. According to Linortek, this architecture eliminates recurring subscription fees common with cloud-based alternatives.
Target Markets and Applications
Linortek has positioned the system for educational institutions requiring class change bells and emergency notification capabilities, manufacturing facilities needing shift management and safety alerts, warehouse operations managing break schedules and visitor notifications, government & commercial buildings requiring multi-zone announcement systems.
The company states that the system meets OSHA requirements for employee alarm systems in industrial settings.
Availability and Pricing
The Netbell IP Paging System is available through Linortek's online store. The company offers pre-configured system kits starting at $958, as well as individual components for custom installations. Package options include configurations for educational facilities, manufacturing and warehouse environments, government buildings for daily voice paging, emergency notification systems, VoIP-integrated systems, and more.
Technical documentation, installation guides, and video tutorials are available through the company's resource portal at resources.linortek.com. The company provides free technical support during business hours.
