I've used 3Com for years and they have always worked well. I am
considering the 4200G. But I am passing on PoE for now. The odds of
actually needing it on this set of switches is small enough that it
isn't worth the extra.

Re: PoE switches?

All depends on the VOIP solution they have, we have Nortel and you can not
tell the difference but the trick is make sure you use QOS of put the IP
phone on their own data network (like we do by vlan'ing).

If you don't plan properly for VOIP, then yes, chances are you are going to
have bad voice quality.

Like most things it totally depends on the implementation. Do it right
and no one can tell. Do it cheap or just throw it in and thats the level
of quality you can expect.

We run IP phones mostly here, seems to work well.

Locally, or over the Internet? I've had countless big providers try to sell
me on their systems only to have the convo fall into buzz-chirp-squawk.
Ironical!

Re: PoE switches?

Exactly. Even the big folks.

One of our tenants with a lot of money implelented it and regretted it
forever.

Phone bandwidth is trivial however compared to gigabit ethernet, and
with QOS it shouldn't really matter. Now without QOS that's an
entirely different issue.

VOIP and IP Telephony generally refer to different things in
conversation. Most people who talk about voip are making calls across
the internet. IP phones on a lan that then go out over a normal t1
voice circuit are entirely something else.

IP inside good, IP outside? Mostly bad with a little good, except for
the people selling it who will tell you it's mostly good and just a few
bad but those people just don't have it set up right and that's not he
fault of the internet which never ever has congestion or packet loss.

And also keep in mind that voice traffic is latency sensitive. Not all
switch manufacturers QoS are (is?) equal.

Swapping out AT switches with QoS with Ciscos with QoS improved our
VoIP experience onsite.

Ok, so we aren't running voip, I sit corrected. <G>

ShoreTel offers both. We went with 100Mb, though, since the 10/100 PoE
blades were cheaper than the 10/100/1000 PoE blades.

How many non-PoE devices do you have now? How many potential PoE
devices are you looking at? May be cheaper to just add PoE capability
later on if it's necessary. That is, unless you just have a single drop
to each location which would mean sharing the same drop for both PCs &
phones. That would of course mean having to replace the switching
infrastructure.

Over the Internet, like with Vonage, is a completely different beast.
You can't guarantee quality with Internet traffic. However, for an
internal phone system you can't even tell the difference in quality.
Actually, I take that back. When our ShoreTel phones use the high
quality CODEC it actually has *better* sound quality than our old TDM
system.
