GSM VOIP Switch

The GSM VOIP Switch from Shen Zhen Runsun Technology Co., Ltd. integrates GSM cellular networks with Voice over IP platforms, allowing enterprises to route calls through both technologies. It is built on a PCI 2.2 and PCI Express 1.0 compliant card that fits standard 4U rack units. The device supports multiple simultaneous GSM channels and provides both FXS and FXO line interfaces for analogue phone connections. Its firmware includes a graphical user interface that can be managed without specialised IT staff.

In the telecommunications market, such switches typically use a metal chassis and operate from a 12 V DC supply with power consumption below 15 W, which helps reduce operating costs. Standard industry practice mandates support for SIP and H.323 signalling protocols, and latency is usually kept under 30 ms to ensure conversational quality. The unit complies with PCI standards, facilitating easy integration into existing server racks. Temperature tolerance generally spans - 10 °C to +50 °C, matching data‑centre environments.

Primary users include telecom operators, hotel chains and healthcare facilities that require reliable backup communication channels. The switch can be deployed in private PBX systems or call‑centre environments to provide redundancy and cost‑effective outbound calling. Shen Zhen Runsun Technology offers flexible minimum order quantities and ships under FOB or CIF terms, but buyers should confirm the exact MOQ and shipping schedule. Prospective purchasers are advised to request certification documents such as CE or FCC to verify compliance with local regulations.
