Likely incrementally better. In your USB port is relatively isolated as it is.
Just like a wireless survey, even if it's not directly LoSing your connection,
the objects between the receiver and transmitter will still cause some signal
attenuation.

I wonder if/how using a USB extension cord would help. So basically having the
end device itself high above cubicle partition walls, away from any materials
of interference.

This is true of almost any Bluetooth though, not exclusive to the 8800 phones.
My old Jabra evolve could go up to halfway through my office on the dongle
either in my 9971 or my PC, but directly paired to my PC it barely went over 3
or 4 cubes down before starting to get choppy. I'm not sure if it's because of
(possibly) internal chipsets being lower powered, the antennae being badly
routed (or increasing loss due to length) and/or loss by going through the
casing of the object itself. Either way, it's always better to use a dedicated
adapter, but in the immediate vicinity of your cubicle or a small office, its
less of an issue.

so you're saying that the bluetooth transceiver built into the 8861 is not as
good as the one you plug in?

Something to note about the 8861/51 and Bluetooth, is that when I pair my
Plantronics Voyager Focus UC directly to my 8861, the quality is not that
great. However, if I stick the included Bluetooth dongle
(BT600<http://cp.mcafee.com/d/1jWVIi6wUSyMY-Yess7cCXCQkmnSkNMV4QsCQkmnSkNPPX9J55BZVYsY-Urhhsd79EVLuWdPp3lpmawECSHIdzrBPpdJnor6TbCXSgSVEVuvW_c8FELnhWZOWrbP_e6zBOXXzDkhjmKCHtxDBgY-F6lK1FJ4SMrLRQkNPaqqar1KVI04IvI9NH2lGsLztcmzl1KQY8jsLsTqlblbCqOmbAaJMJZ0kIToHMd9_7wqrhuphhdwLQzh0qmXiFqFsPmiNFtd40BaBGCy1VVZ4Qgr10Qg39XvPHmpcQg32TWl-9JwQsCYJ50GQ_WMd6S>)
into the side of my 8861 first, then pair with the dongle, the quality is
pretty great.
So, for whatever the reason for my experience, the 8861 cannot meet the high
quality demands I have, on its own, without the dongle. This might be true for
you folks looking to get the 510 as a speaker phone too. I.e., You should use
it plugged into the phone via USB, instead of using Bluetooth. Maybe.

The 8800s are the only bluetooth endpoints that support wideband audio.
I wouldn't bother using bluetooth on anything else unless you are a g729 shop
or in general don't care about audio quality.

We've been using the speak 510's for just this reason and they've worked out
OK.. actually started using them with 8945's initially but bluetooth seems to
work better on the 8800's, anecdotally.
I haven't been thrilled with the 8831. Internal customers don't care for the
form-factor and they haven't been as reliable as the 7937's for us.

Has anyone tried to use the Cisco 8851 and a Bluetooth speakerphone as sort of
a poor man's conferencing set? The sets themselves sound pretty good on their
own, but, something like the Jabra Speak 510 that is Bluetooth enabled would be
a more cost effective option than the $900+ 8831 set (which still has an
unresolved bug causing the Conf button to randomly fail anyways).
It is obviously not explicitly called out as supported, but, anyone tried this
and had any success? Or, any recommendation on a 3rd party conferencing phone
that is more cost effective, even if not as capable, for a smaller (6 - 8
person) conference?
