Subject: Re: Linksys WIP 330 VoIP wireless phone crash
	fromNmap scan

Hi,

Yes, this is an extraordinarily lame bug, but that's sort of the point
with many of these VoIP phones, both wired and wireless.  They are a
new class of device going onto networks and tend to be kind of sucky
when it comes to what I'd consider *expected customer environment tool
runs* like Nmap and Nessus, not to mention plenty of others such as
ISIC, Protos, Asteroid, <insert fuzzer-o'-the-day-here>...and that's
just sticking with the free stuff.

I didn't find the bug anyways, I just reported it to Linksys and then
FD.  And even though I'm poking around with a bunch of VoIP phones on
my own time and dime, I don't own one of these WIP 330s.

Anyway, you seem happy with your WIP 330...once you got it configured...

Say, if you have the cycles for some free vendor QA, and since you
have a WIP 330 in hand, maybe you can find something much cooler with
that PhoneCtl.exe crash and get back to us?

Thanks,
--scm
