The WinVP-3022 SOHO Gate is a H.323 compliant highly integrated stand-alone broadband VoIP router with 4 analog voice interfaces and 4-port Ethernet Switch dedicatedly designed for enterprise branches, SOHO and residential users. WinVP-3022's state-of-art system design seamlessly bridges voice applications over legacy telephone network (PSTN) and Internet through broadband access, such as xDSL, cable modem and FTTH (Fiber To The Home) without additional software required. In addition to voice applications, WinVP-3022's embedded NAT router function can also converge data applications in the same box over a single Internet connection.

Key Features and Benefits

H.323 NAT
Most of NAT cannot work very well at VoIP answering mode. WinVP-3022's H.323 NAT has the functions of a normal NAT, plus it provides IP address translation for H.323 standard based terminals, such as IP Phone, NetMeeting enabled PC, which solves the single IP problem in VoIP applications.

Quality of Service
The Quality of Voice over Internet is the critical factor. WinVP- 3022 VoIP Gateway
follows 802.1p and Type of Service (ToS) feature. When interfacing to a very unstable Internet environment where it is most likely to encounter a 20% packet loss rate, users may hear chopped, low-quality voice. The unique robust voice recovery algorithm can
largely compensate the packet loss rate effect of the Internet and give users a stable voice quality.

Traffic and Bandwidth Management
Work along with built-in QoS and ToS functions, WinVP-3022 can efficiently control and manage the traffic and bandwidth by various policies, such as port numbers (FTP, HTTP, Telnet, etc), IP addresses, etc, and providing varying priorities before transmitting to the Internet. It considerably enhances the quality of services, especially reducing voice latency, and improving network efficiency without the need of extra expensive traffic management box.

Life-line
When you encounter device power failure or crash condition, most VoIP gateways cannot deliver back-up feature to insure undisrupted voice service. WinVP-3022 however, offers a robust zero-loss "life-line" design, with which you need not worry about power failure any longer. During power or device failure, the voice calls are nevertheless transparently pass to PSTN.

Intelligent Call Routing
WinVP-3022 supports innovative intelligent call routing function that transparently routes calls to the called destination either through PSTN or Internet. The end user simply dials the destination number without altering the original dialing behavior. WinVP-3022 can detect and distinguish the dialed number and take the most efficient routing path to rout the number automatically.

Dynamic IP Support
The VoIP gateways available in the market today require fixed IP address to determine its location in the Internet. That causes inconvenience to many dial-up and broadband VoIP applications users those don't have fixed IP address. The WinVP-3022, however, allows existing addressing schemes to remain without the need of fixed IP address. WinVP-3022 can directly connect to DHCP enabled cable modem, or PPPoE equipped ADSL modem, which uses dynamic IP address to link to Internet.

Management Tools
WinVP-3022 supports full remote management ability with its embedded Telnet server, HTTP server and SNMP agent. The network manager can easily control and monitor the gateway from any point in the world through a convenient web browser or telnet client. Plus, WinVP-3022 also provides a real-time "voice call monitoring" interface. It helps the system administrator constantly aware of all the call statistics.
