I agree, GrandStream does seem to become the poor man's VoIP solution -
making the bar for other VoIP phones very low to pass.
I believe that GrandStream have a very good chance to basically being
bought by a bigger company, like what happened to Sipura. What
would happen then would be that people would say: "Oh, GrandStream, Very
good - after all XXXX bought them".
I found that sometimes the most surprising hardware comes from non-known
companies, like PerfecTone or Micronet. I think the main
thing is the try things out, and find out what is the best suited IPhone
for you.

I think the unfairness stems from Grandstreams generally being
people's first IP phone - it seems like a cheap entry point to try
things out. They then falsely assume everything else has to be better,
especially if it has a higher price tag. Wrong. The standard for VoIP
phones is total crap. Anything rising even slightly above that level
wins awards for excellence. :-)

Hmmm...
I feel that this is a little unfair towards GrandStream and other
like vendors. Any vendor on the market has issues with their
firmware, I can list many:
Sipura/LinkSys SPA 841 (Latest firmware):
1. Phone doesn't re-register upon network loss
2. Phone firware becomes stalled, without any indication of an error
while all functions continue working
3. Transfer function doesn't work as it should
4. MWI doesn't always work correctly
5. I can really go on and on...
WellTech (Latest firmware):
1. Support for g729 is buggy
2. Echo cancel is buggy and causes ATA to crash
3. IP phones have no ability to re-configure the function keys on the
box
4. Transfer/Conference buttons don't do anytning
I can go on and on with other vendors, including Cisco, Nortel and
more. The thing I'm saying is that any phone you'd test would run
into issues at some
time or other - claiming to stay away from one or another causes you
to not even consider alternatives, thus at the end, you reach the
Microsoft way of
thinking.
Last week, I got a phone to test with called a MicroNet. Actually, I
got 3 phones, all from Micronet. I started them up, found out that 2
of them were
actually WellTech phones (well, the shape told me, I hoped the
firmware will be different, but I found out wrong). The third phone
was different. It's called
a Micronet SP5106 which to my surprise, worked almost flawlessly out
of the box. It took me a while to configure the network correctly,
and to understand
the logic of the menu, but after that, the rest was easy. Transfer,
3-Way conference, Forward, DND, VoiceMail button, everything worked.
What didn't
work was configurable from the web backend - in other words: I
couldn't find a flaw (yet). The only flaw I did find was this: the
phone has the ability to
connect to 3 SIP accounts at the same time. Upon defining a new
account, you need to physically RESET the phone, other than that, the
phone works
just fine.
I'll be posting a full review on my blog at http://www.net-gurus.net

Stay away from Grandstream and AddPac. These are some of the
companies with undereducated software developers that have problems
with understanding written english, mainly the SIP RFC documents. I
learned this the hard way, wasting half a year with helping them fix
problems which shouldn't be there if they have had read/implemented
the RFC correctly.
Basically, they sell beta quality hardware and then you co-share
their final firmware development costs by providing free testing/QA.
I blame their sales management for pushing developers to release
without proper testing.
GXP2000 is much more buggy echo-can wise than the earlier models.
For now, I'm back to more expensive equipment. We're not that rich
to pay twice.

I have 4 of them in a small office (GXP2000) running 1.0.12 and
they're just fine for our purposes. As Brian said, YMMV. For our
60-person office in Sydney, I'm probably going to use a mix of
Polycom/Grandstream and softphones.
