=====|===== | DESCRIÇÃO DO PRODUTO | =====|=====

PLANET VIP-281 This is a 2-Port VoIP Gateway (1*FXS + 1* FXO) - SIP/H323 Dual Protocol which is fully compliant with both SIP and H.323 standard residential gateways that provide a total solution for integrating voice-data network and the Public Switched Telephone Network (PSTN). This can handle both SIP and the H.323 calls and can make calls to either H.323 or SIP voice communication environment.

Network Features
Network Address Translation (NAT)
NAT allows multiple PCs to connect to an Internet Service Provider (ISP) using a single Internet access account
Point-to-Point Protocol over Ethernet (PPPoE) Client Support
If you are a DSL user, the router has a built-in PPPoE client for establishing a DSL link connection with the ISP. There is no need to install a further PPPoE driver on your computers
Smart QoS
The smart QoS provides stable voice quality while user access internet from private LAN to internet at the same time. This device would start suppressing throughput automatically when VoIP call proceed and keep full speed access when there is no VoIP traffic
DDNS (Dynamic Domain Name Server)
DDNS is a service that maps Internet domain names to IP addresses. It allows you to provide Internet users with a domain name (instead of an IP Address) to access your Virtual Servers
Virtual Server
Remote Users can access services such as the Web or FTP at your local site via public IP addresses that can be automatically redirected to local servers configured with private IP addresses
