The VIP-281SW wireless router not only provides the highest quality voice calls and shared Internet access, but also functions as a wireless network access point. Thanks to the advanced VoIP DSP processor, the device allows you to make voice calls via SIP Proxy and share IP addresses, and also offers a QoS mechanism.
With the VIP-281SW, home users and businesses can reduce installation costs and reduce investment in telephony and conferencing equipment. VIP-281SW is equipped with two telephone lines - users can register with different SIP proxy servers and make 2 simultaneous VoIP calls. With very little investment, the VIP-281SW can serve as a bridge between the traditional analog telephony system and the IP network.
Thanks to the built-in wireless access point in the IEEE 802.11b/g/n standard, the device offers wireless Wi-Fi connectivity with a data transfer rate of up to 300Mbps. Also, the range of the network has been doubled, allowing you to connect at the highest possible speed even in open spaces.
To secure wireless connectivity, the VIP-281SW supports the latest encryption mechanisms: WEP, WPA-PSK and WPA2-PSK. In addition, the VIP-281SW allows WPS configuration to easily connect users by pressing a button on the device or entering a PIN code.
