תאור:

The DVG-4088S is a 19“wide, rack mountable VoIP gateway that 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 with all well known Soft Switches and SIP proxy servers. While running optional server software, the gateway can be configured to establish a private VoIP network over the Internet without a third-party SIP Proxy Server.

The gateway can be seamlessly integrated into an existing network by connecting it directly to a phone set, PBX, key telephone system, fax machine or PSTN line. With only a broadband connection such as an ADSL bridge/router, Cable Modem, or leased line router, the gateway allows you to access voice and fax services over IP which significantly reduces the cost of international and long distance calls.

QoS functionality allows voice and data traffic to flow smoothly while voice traffic is accorded the highest priority. With the TOS bit enabled, the gateway guarantees voice packets will have first priority to pass through a TOS enabled router.

DDNS support makes the gateway accessible using its domain name when IP addresses are dynamically assigned by the ISP. This capability helps users host a website or mail server in a PPPoE or DHCP network. By enabling the CDR function and setting up a simple server, administrators are allowed to log and view all call records including call duration, time and date of calls, and latency..
