It appears that Linksys is finally ready to make its move into the Voice over WiFi market with its own Wi-Fi VoIP phone. And, as should be expected from an industry leader, Linksys' offering has important features to separate it from an increasingly-crowded field and to make it more friendly to corporate networks.

As its name implies, the WIP330 Wireless-G IP phone has an 802.11b/g radio. This will allow it to operate on 802.11g networks without the throughput impact caused by slower 802.11b-based phones. In addition, the WIP330 appears to be the first VoIP Wi-Fi phone to support both WEP encryption and stronger WPA-PSK wireless security, but there is conflicting information in the User Guide. The specification section lists "WEP (64/128), WPA-PSK Encryption" for the Security spec. But the manual's section describing wireless setup refers only to entering a WEP key and has no reference to WPA-PSK.

The phone supports SIP v2 with G.711 u/A-law and G.729a/b voice codecs and ToS (Type of Service) QoS. Voice quality features include Acoustic Echo Cancellation, Jitter Buffer Control, Comfortable Noise Generation and Packet Loss Concealment.
