RE: Wifi SIP WPA/PSK Support

  • From: Casey Halverson
  • Date: Thu Jan 26 18:13:26 2006

I have actually been following this as well, and I have tested several
of these handsets.  Others have been impossible to source.  Typically
startups will attempt to bring a wifi voip handset to the market,
realize there is no demand, and fold.

In the particular discussion of WPA:

Note that the two Senaos listed claim WPA support, but this is not
available in the current firmware.  There also hasn't been any updates
to it in a year or so -- don't expect it anytime soon.
