WiFi phones enable you to make SIP VoIP calls by using IEEE 802.11b/g wireless standards.
You now can use your WiFi phone to receive and make VoIP calls from any place where a high-speed wireless internet access is available; whether it's at your home, place of business or your neighborhood's enternet caf
With a WiFi phone, you stay connected where ever you are. There is no need to stay at your fixed IP phone or ATA device.
