VoIP Wi-Fi Phone Enjoy the Benefits of VoIP, Wirelessly Model. .. P-2000W_V2 Benefits Mobility and Availability The call control protocol of the P-2000W is based on SIP v2 (Session Initiation Protocol version 2, RFC 3261) open standard, which is interoperable with major SIP-based call servers, IP-PBXs, and other standard SIP-based client devices. The P-2000W_v2 is compliant with the IEEE 802.11b standard and interoperates with any existing 802.11b or 802.11g wireless AP and gateway. It may be used as a cordless handset for residential users or for business users in an office environment. The small form factor of the handset is easy to transport and allows users to place VoIP phone calls in public 802.11-based environment. High Voice Quality with Low Communication Costs The P-2000W_v2 is capable of tagging features that support a service provider\'\'s QoS (Quality of Service) planning, such as ToS (Type of Service). It allows gateways or central side equipment to identify and prioritize voice and data traffic. By supporting G.711 and G.729 voice compression technology, the P-2000W_v2 effectively reduces bandwidth consumption caused by voice traffic. Travel Charger Design for Mobile Users The P-2000W_v2\'\'s travel charger design makes it easier for users to carry and use the phone in different site. The mobile phone style design also let user to have similar and better experience to use VoIP service. Direct IP-to-IP Call and Ad-hoc Intercom Mode Support By configuring a remote IP address in the built-in phone book, the P-2000W_v2 provides a direct IP-to-IP call feature when there is no intermediate SIP proxy server available in the network. The P-2000W_v2 an also establish an 802.11 ad-hoc network (computer-to-computer network without Access Point), which allows users to use the handsets as wireless intercoms.
