» Industry’s latest Voice over the IP

network protocol

» Compatible with popular SIP Internet

phone services.

The IP phones allow Internet subscribers to take advantage of their DSL/cable modem

connection to make inexpensive Internet phone calls. By utilizing the IP phones with

a VoIP service plan, home and business users have the potential to dramatically

reduce local and long distance telephone charges compared to a standard telephone

service.

The IP phones combine the industry’s latest Voice over the IP network (VoIP)

technology with advanced communication features, and are compatible with industry-

wise phone service. They give callers the advantages of VoIP, while retaining the

same look and feel of the familiar analog telephones.

The IP phones are stand-alone devices and do not require connection to computers

to operate. They provide Ethernet ports for direct attachment to DSL/cable modems,

or to home or office routers with Internet connection. Once they are connected to

the Internet, these IP phones are ready for users to make and receive calls. The IP

phones incorporate Quality of Service (QoS) and other VoIP features to ensure that

voice received through the Internet is the same as or even surpasses that received

on the ordinary phone.

The Wi-Fi phones are IP phones with built-in WLAN interfaces. They provide the

freedom of wireless connectivity and the benefits of Voice over IP (VoIP) all in one sleek

portable flip-style phone. With a growing number of Wi-Fi hotspots and metropolitan

areas deploying low-cost or free high-speed Internet connection, and widespread use

of LAN switches supporting 802.11 wireless LAN in enterprise networks, mobile users

will have more places to use the Wi-Fi phones. Applications include making Internet

phone calls at an Internet cafe, from a car or truck in a parking lot equipped with hot

spots, or in an office building while roaming around different floors.
