VoIP SIP Gateway

Overview
	The 2/4/8 ports stand-alone VoIP Gateway carries both voice and facsimile over the IP network. It supports SIP industry standard call control protocols. As a standard user agent, it is compatible to all well-known Soft Switches, SIP proxy servers. While running the optional server software, the gateway can be configured to establish a private VoIP network over the Internet without a 3rd party SIP Proxy Server. There are different models available for different applications. The gateway can be seamlessly integrated to existing network by connecting to a phone set, PBX, key telephone system, fax machine or PSTN line. With only a broadband connection such as ADSL bridge/router, Cable Modem or leased line router, it allows you to gain access to voice and fax services over IP in order to reduce the cost of international and long distance calls. In addition, the in-built port switch supports comprehensive Internet gateway functions to accommodate other PCs or IP devices to share the same broadband stream. QoS function allows voice and data traffic to flow through where voice traffic is transmitted in the highest priority. With TOS bit enabled, it guarantees voice packets to have first priority to pass through a TOS enabled router. With the support of DDNS, it makes the gateway reachable by its domain name where the IP address is dynamically assigned by the ISP. It helps users to host a web site or mail server in a PPPoE or DHCP network. By enabling the CDR function & setting up a simple server, administrators are allowed to log and view all call records such as call duration, time and date of calls and latency, etc.
