    BM430 Industrial Telephone Mainboard for SIP Intercom, Paging, and Emergency Communication

    Built for industrial communication product development, BM430 helps manufacturers and solution providers quickly build SIP industrial telephones, weatherproof intercoms, tunnel emergency phones, campus help points, alarm boxes, paging microphones, and security communication terminals. Its flexible interfaces make it suitable for both standard telephone products and customized enclosure-based communication devices.

    Product Overview

    BM430 adopts a mature VoIP architecture and supports standard SIP communication. Media transmission is based on IP, RTP, and RTSP protocols, allowing the board to connect with SIP servers, IP PBX systems, dispatch platforms, intercom systems, and paging solutions. The board supports two SIP lines, making it suitable for emergency calling, normal communication, broadcast linkage, and dispatch integration.

    The mainboard supports digital full-duplex hands-free communication, providing clear and loud voice performance for industrial environments. It can use an onboard 3W speaker output or connect to an external amplifier board through the audio line output interface, allowing customers to design products for different sound coverage requirements.

    Key Features of BM430

    Integrated SIP Communication Platform

    BM430 supports SIP 2.0 communication and can be registered to SIP servers, IP PBX systems, or dispatch platforms. It supports two SIP accounts, allowing one device to handle multiple communication scenarios such as emergency call, intercom call, dispatch call, and paging call.

    The board supports common voice codecs including G.711a/u, G.723.1, G.726, G.729A/B, iLBC, G.722, and Opus. This helps ensure flexible compatibility with different SIP platforms and audio environments.

    Audio, Video, and Intercom Functions

    BM430 supports hands-free speaker, hands-free microphone, handset interface, audio line output, and camera interface. It can be used to develop audio-only or audio-video industrial communication terminals according to project requirements.

    With H.264 video decoding and QVGA video support, BM430 can be used in SIP video intercom products, emergency call stations with camera modules, access control communication terminals, and visual dispatching applications.

    Flexible Interface Design

    BM430 provides rich hardware interfaces for customized industrial telephone design. These include display interface, keypad matrix interface, handset interface, hands-free speaker interface, hands-free microphone interface, audio line output, hook detection, camera interface, RS485 interface, relay input/output, dual RJ45 Ethernet ports, DC power input, and optional WiFi antenna interface.

    The 6×6 matrix keypad interface supports up to 36 keys, including number keys, navigation keys, function keys, volume keys, mute key, video call key, hands-free key, and programmable DSS speed dial keys. This makes the board suitable for products with simple emergency buttons as well as full-keypad industrial telephone terminals.

    Typical Applications

    SIP Industrial Telephone

    BM430 can be integrated into wall-mounted industrial telephones, weatherproof telephones, cleanroom telephones, railway phones, tunnel phones, and factory communication terminals. The board supports handset and hands-free modes, allowing product designers to build different telephone structures for different use environments.

    Emergency Call Station

    BM430 is suitable for emergency call boxes, help points, SOS stations, and alarm communication terminals. Through SIP calling, programmable keys, relay interfaces, and optional camera integration, it can connect field users with control rooms, security centers, or emergency dispatch platforms.

    SIP Paging and Intercom Terminal

    With audio line output and external amplifier support, BM430 can be used in SIP paging microphones, paging call stations, broadcasting terminals, and integrated intercom-paging devices. It can support voice communication, broadcast triggering, monitoring, and dispatch linkage.

    Industrial Security and Access Communication

    The camera interface, relay control, RS485 interface, and SIP video function allow BM430 to be used in industrial access intercoms, security terminals, gate communication points, and monitoring-linked emergency devices.

    Web-Based Configuration

    BM430 supports web management for easy configuration and maintenance. Users can log in through a browser to configure SIP account information, server address, port, username, password, speed dial keys, audio volume, microphone gain, handset volume, and audio line output settings.

    The board supports online software upgrade and factory reset. The default static IP address is 192.168.1.128, and network settings can be changed through the web interface, IP scanning tool, or local keypad menu.

    LED Status and Maintenance

    BM430 provides LED status indication for power, registration, network, call status, and keypad working status. The power LED indicates whether the board is powered. The network or registration indicator can show registration success, registration failure, network abnormality, or call status. These visual indicators help installers and maintenance engineers quickly identify device status during deployment.

    Factory reset can be performed through the web interface or by long pressing the reset key for 6 seconds in standby mode. This allows the board to return to default settings when reconfiguration or troubleshooting is required.

    Why Choose BM430 for Industrial Telephone Development?

    BM430 is designed for manufacturers and integrators who need a reliable embedded communication platform for industrial telephone products. Instead of developing SIP audio, keypad, display, camera, relay, and web management functions from the beginning, BM430 provides a ready-to-integrate mainboard platform that can shorten product development cycles and improve system stability.

    Its compact size, rich interfaces, wide operating temperature range, SIP compatibility, dual Ethernet ports, optional WiFi, and flexible audio expansion make it suitable for harsh industrial environments and customized terminal products.

        BM430 is not only a telephone mainboard. It is a flexible SIP communication core for industrial intercom, emergency calling, paging, alarm linkage, and customized communication terminal development.

    BM430 Application Scenarios

    BM430 can be used in factories, tunnels, rail transit systems, campuses, mines, chemical plants, substations, public safety sites, emergency communication points, parking facilities, access control areas, and industrial parks. It is suitable for projects that require reliable SIP voice communication, fast emergency calling, paging linkage, and dispatch system integration.

    For Becke Telcom industrial communication solutions, BM430 can serve as the embedded mainboard platform for customized SIP industrial telephones, weatherproof call stations, emergency intercom terminals, paging microphones, and audio-video communication devices.
