Overview

The IDM-G2000 is a 4-8 channel (4-8 SIM Card) broadband telephony gateway newly developed by Beijing Raytrans Digital Technology Co., Ltd. By installing mobile SIM cards into the G2000, users can register GSM telephony to a VoIP softswitch system. Through the GoIP, users can achieve on-ramp and off-ramp access to the GSM network. Flexible routing functions meet the special requirements of various call forwarding scenarios; the G2000 adopts a modular structure design with strong adaptability, low power consumption, and high reliability.

In the era of rapid wireless development, wireless applications are becoming increasingly prevalent; and as traditional PBX systems are gradually being replaced by IPPBX, the G2000 enables seamless connectivity between IPPBX and wireless networks. Enterprises can reduce communication costs by selecting favorable wireless tariff packages, while mobile network operators can effectively acquire high-value voice enterprise customers through wireless bypass strategies, providing a reliable platform for consolidating and developing enterprise mobile users. The G2000 provides a perfect integration between GSM/CDMA and VoIP.
