Ooma tells me speed & jitter are ok but I have 0.25% packet loss.
 
What happens, as a result, is that in any given phone call, the voice
drops, or is blurbled, for seconds at a time.
 
I don't quite understand how losing one packet in 400 on average is causing
that, but they said take it up with the WISP who has already said it's as
good as he can make it.
 
Ooma suggested a new cordless phone set. Is there a cordless phone set
you're happy with? The base MUST be a full phone (speaker + dialer + wired
handset) with as many cordless as is feasible (usually 2 to 4 come with the
set).
 
Ooma tells me packet loss should be 0% ... do you have a good test for
that? (Ooma didn't have a test we could run.)

God help us, its a PHONE! All that is necessary is to be able to understand the occasional actual caller. Any given Panasonic/AT&T/Samsung cordless set will do the trick with neither agony nor anxiety attached. Should be in the $30 - $50 range for a system with, perhaps, three or four remote sets with it. Just pick an open frequency when you set up. The typical phone has 16 options. Some more.
 
Sheesh!

In the 1960s, transistor radios and came supplied with crystal earpieces.

I'm sure it does if you're in the right field, but the world I live in
doesn't do Apple. If we do something for iPhones it is only as
peripherals. There may be emergency dispatch centers that run on os x
but I don't know of any. Generally the RFQ's spec Windows Server, SQL
Server, ESRI, and so forth. Even ESRI is a killer; ArcDesktop can run on
a Mac -- sort of. Fire up Boot Camp or VMWare and run Windows.
 
I did work on one project that used Macs although I was not involved in
that part. The early Mac that was a cube was the only thing that could
meet TEMPEST requirements.
 
I'm sure you will reel of all sorts of counter examples but I've always
associated Apple with consumer oriented devices and software and that's
not been my meal ticket.

Therein lies the rub in our business model. We're doing proprietary
applications for a very limited audience and the app store is not the
way to go.

Ah, yes, the simulator... Snore...

I never said it was. However it is an Android device that I can side
load an apk on.

you didn't mention proprietary apps, however, there are alternative
methods for app deployment that do *not* involve the app store at all
for exactly that scenario. the app store is not the only option.

you've never used it, so you're not in a position to comment.
 
it was simply a suggestion for those who *really* want to cheap out.

yet you compared its price to an iphone or ipad.
 
the reason it's $50 is because its specs are lower.

that would depend on what the apk does. if it needs functionality not
found in a $50 device, you're going to have problems.

the cube was a *long* time ago.

there's nothing wrong with focusing on consumer products. it's a *huge*
and *very* lucrative market, although apple is not solely consumer
focused.
