Product Introduction

The BK-W712 is a wireless cluster access gateway that integrates built-in radio and SIP modules, core to its ROIP and SIP dual-protocol support. Its core value lies in bridging analog/digital two-way radios and SIP communication devices, including SIP phones and SIP-based fusion communication platforms. The gateway is fully compatible with mainstream analog and DMR II digital two-way radios, a key design that allows businesses and security teams to retain their existing radio equipment while connecting it to modern SIP communication systems, significantly reducing the cost of communication system upgrade and transformation.

Physically compact and portable, the BK-W712 features a user-friendly deployment and management design, suitable for both fixed installation in central control rooms and temporary deployment in mobile emergency scenarios. Unlike traditional gateways that rely on a fusion communication platform for operation, the BK-W712 can work independently, providing flexible communication support for small and medium-sized scenarios with simple communication needs or temporary emergency communication requirements. Whether used as a standalone device or integrated into an emergency command fusion communication platform, the BK-W712 can stably connect various wireless radio communication systems, realizing unified scheduling and interconnection of communication resources.

Core Communication Capabilities

Single Call

Single Call
At the single call level, the BK-W712 supports 1:1 interconnection between one analog/DMR II digital radio and one SIP call terminal, enabling direct voice communication between a radio user and a SIP phone user. This function is particularly practical for daily work coordination, such as a security guard using a radio to directly contact an office staff member with a SIP phone in an industrial park.

Group Call

Group Call
For group call scenarios, the gateway realizes cross-system group communication between analog/digital intercoms and SIP phones. In security patrol or industrial production scheduling, a single radio group call can be received by all members of a corresponding SIP phone group, and vice versa, ensuring that scheduling commands are transmitted to all relevant personnel in real time, improving the efficiency of group collaboration.

Trans-regional Communication
