Introducing the ZyXEL Prestige 2000W

ZyXEL's P-2000W VoIP Wi-Fi phone, compatible with IEEE 802.11b wireless standard, is a perfect solution for Voice over IP applications. It allows users to make or receive phone calls as long as they are in the coverage of IEEE 802.11b or 11g wireless Access Points. By using the P-2000W, users no longer have to pay expensive communication fees and can enjoy the convenience of wireless mobility.
The brand new application is developed to support open standard SIP (Session Initiation Protocol), which interoperates with major SIP-based call servers, IP-PBXs and various VoIP client devices. It is not only an ideal alternative for ITSPs (IP Telephony Service Providers) to deploy their VoIP services; it can also be the wireless handset, which is applied in corporate IP-PBX centric VoIP environment.

ZyXEL's P-2000W is very easy to use and configure. It allows users to configure with LCD screen menu or web browser. Meanwhile, with the smart auto-provisioning mechanism, ITSPs can easily deploy and manage the VoIP services. Easy-to-use and convenient, the P-2000W delivers high quality voice functionality in a cost-effective way.


Open Standard SIP v2 Support
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.

Mobility with IEEE 802.11b Wireless Standard Compliance
The P-2000W 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 hot spots.

High Voice Quality with Low Communication Costs
The P-2000W is capable of tagging features that support a service provider’s QoS (Quality of Service) planning, such ToS (Type of Service) and DiffServ. 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 effectively reduces bandwidth consumption caused by voice traffic.

Enhanced Power Saving Design for Extended Standby and Talk Time
With an improved power-saving design, the P-2000W can be used for a relatively long period of standby and talk time. With an extended life for each recharge cycle, the P-2000W is available where and when you need it.

Direct IP-to-IP Call and Ad-hoc Intercom Mode Support(Optional)
By configuring a remote IP address in the built-in phone book, the P-2000W provides a direct IP-to-IP call feature when there is no intermediate SIP proxy server available in the network. The P-2000W can 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.
