VoIP | LSB Gateway Overview
Product Overview
LSB is a 2/4/8 ports stand alone VoIP Gateway which transmits real time voice and fax data over
IP networks. By deploying RoboGate, all voice and fax calls can be routed through the Internet and the long
distance call charges can be eliminated. Supporting various types of Internet access, such as an ADSL,
cable modem and leased line, RoboGate can provide value added voice application over the company's existing data network. Easily integrated into any PBX system, RoboGate provides immediate cost saving without any impact on the company's telephone system.
In addition, the built-in NAT router provides Internet sharing function to other PCs or IP devices in the same network. Smart QoS function allows voice and data traffic to flow through where voice traffic is transmitted in highest priority. Furthermore, the gateway is standard based and fully compliant with other SIP or H323 VoIP products.
