BM13 is an embedded phone board and tel board designed for SIP phones, IP intercoms, paging terminals, emergency phones, help points, and customized voice communication devices. It provides a compact IP voice control platform for manufacturers and system integrators developing network-based communication terminals.
With its compact hardware design and flexible interface options, BM13 can be integrated into wall-mounted SIP phones, industrial telephones, clean room phones, vandal-resistant phones, emergency call stations, paging call stations, and broadcast intercom terminals. It helps reduce development time while supporting stable SIP voice communication, audio control, external device linkage, and centralized deployment.

BM13 is suitable for OEM manufacturers and project-based terminal development. It can be used as the core phone board inside different enclosure designs, helping manufacturers focus on product appearance, application functions, and final system integration.
BM13 supports enhanced audio output for hands-free calling, intercom, and paging applications. It helps improve voice playback volume in factories, tunnels, equipment rooms, warehouses, parking areas, transportation facilities, and other noisy environments.
BM13 provides interfaces for keypad control, LCD display, LCD backlight, button backlight, I/O output, short-circuit input, RJ45 network connection, DC power, and device status indication. It supports terminal designs ranging from one-button emergency phones to multi-key SIP telephones.
BM13 supports SIP-based voice communication for IP phones, SIP telephones, intercom terminals, and paging devices. It can work with IP PBX systems, SIP servers, VoIP gateways, dispatch platforms, paging systems, and unified communication platforms, making it suitable for both standalone terminals and system-level communication projects.
BM13 supports narrowband and wideband audio codecs such as G.711, G.729, G.726, iLBC, G.722, and L16. It also supports VAD, CNG, AEC, PLC, AJB, and AGC for stable hands-free voice communication.
BM13 supports multicast paging groups, configurable receiving priority, interrupt paging, and IP address direct calling between reachable devices. This makes it suitable for local paging, broadcast, and device-to-device communication scenarios.
BM13 supports IPv4, IPv6, OpenVPN, STUN, Rport, DNS SRV, HTTP/HTTPS web management, DHCP options, Syslog, auto provisioning, TR069, and batch configuration. These features help simplify deployment and maintenance in large projects.
BM13 supports TLS, HTTPS, SRTP, MD5/MD5-SESS authentication, and AES encryption to help protect SIP communication and system configuration access.

BM13 can be used as the core phone board inside SIP phone and IP telephone products. It is suitable for wall-mounted phones, industrial phones, clean room phones, public telephones, rugged phones, and customized IP telephone terminals.
BM13 can be integrated into IP intercoms, emergency call stations, help points, elevator phones, and one-button calling terminals. External buttons, indicators, alarm devices, speakers, microphones, and control systems can be connected according to different project requirements.
BM13 is suitable for paging terminal and broadcast call station development. It can be used in paging panels, broadcast intercom stations, area call terminals, and emergency notification devices for factories, campuses, tunnels, hospitals, warehouses, transportation stations, and command centers.

BM13 provides a practical phone board and tel board platform for OEM manufacturers, system integrators, and communication equipment developers. It supports fast development of SIP phones, IP intercoms, emergency phones, paging terminals, industrial telephones, and other customized voice communication devices.
For projects that require a compact SIP phone board or IP tel board, BM13 offers a reliable embedded foundation for product customization, system integration, and long-term field deployment.
