The ZyXEL P-2000W V2 VoIP WiFi Phone
We have all seen the ads on TV or on the Web - VoIP phones are all the rage. Voice over Internet Protocol phones allow phone calls to anywhere from your computer and the pricing policy is aggressive and much cheaper than land lines or cell networks.
Enter the ZyXEL WiFi phone – it is sort of VoIP with a twist.
What if you didn’t need a cell phone? With WiFi just about everywhere – what if you had a WiFi phone that could call anywhere using any WiFi hotspot or connection? The idea sounds like a great one…. but in theory.
This is the possibility of handsets like the ZyXEL P-2000W. This phone is based on the SIP (version 2) open standard and should allow you to do just what I suggested in the previous paragraph.
The Technical Data is a little overwhelming – but here is the “official line” from the manufacturer:
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.
