If you want a phone that is compatible with the wireless standard IEEE 802.11b then try the Prestige 2000W from Zyxel, it’s a voice over IP phone and is wireless so welcome to the age of cheap calls.
Its combatable with most SIP call severs and is very easy to set up and configure.
Some Of Its Features Include:
There is a direct IP to IP Call Feature
2.400 And 2.497 GHZ Frequency
A Power Output of 14 + 1dBm
Can Operate At a Range of 300m Indoors or 75m Outdoors
VAD Which Stands For Voice Activity Detection
There’s Silence Suppression
A Standby Time of 24 Hours an a Talk Time of 4 hours
An LCD Screen Display
This is one of the most useless reviews I have ever read. The range is 75 metres inside and 300 metres outside. Standby time is about 11 hours; talk time is 1 hour. The phone is compatible with 802.11g, not just 11b. The phone is not easy to set up and configure. It isn’t hard, either, but don’t expect to be able to do it unless you know a lot about VOIP.
