<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>We have 50 Grandstream's that we purchased about 3 months ago.
They're all at one site and we've had nothing but trouble with all the
phones. The echo is the worst problem of all. We had to upgrade
from the default <a href="http://1.0.1.9">1.0.1.9</a> firmware to the <a
href="http://1.0.1.12">1.0.1.12</a> "beta" to get the
speakerphone to work properly. Once we did that, there is now a bad
echo if one of the GXP users turns their volume up too high, the other party
can hear an echo. If the GXP user turns their volume down a
bit, the echo starts to go away. This happens internally from GXP to GXP
as well as with outside callers. At first Grandstream didn't want to
admit that they knew about this or that they'd even ever heard of this problem
before. But they finally at least said they would have an engineer check
into it. Then after some research online I come to find that lots of
people are having the echo issue with the newer firmware and they had also
notified Grandstream months ago. So they know about the problem. <o:p></o:p></span></font></p>

<div>
<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>On top of the echo issue, which is completely unacceptable, we've had a
couple phones flat out die, we've had several that had the PoE go dead so we
were forced to use the AC adapter. And many of the other phones suffer
from all kinds of stupid little intermittent issues such as dropped
calls, reboots and strange ticking and static on the line, even on
internal calls. We discovered that quite a few of the network cables that
came with the phones seemed to be faulty, which when replacing them seemed to
solve some of our dropped calls and spontaneous reboot problems.
Some of the phones had bad handset cables. Replacing some of those
seemed to get rid of some of the static issues. We've replaced several of
the really troublesome phones with Cisco's or Polycom's, and what do you know,
no problems whatsoever. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

the phones and especially unhappy with the level of service from Grandstream.
Grandstream should not be permitted to sell these phones to consumers, marketed
as a business class phone of all things! They're knowingly selling a
faulty product. It's outrageous. And what's even more amazing
is they claim that the GXP2000 won some sort of award, and it's even a
"Best Seller" at <a href="http://Atacomm.com">Atacomm.com</a>.
How it the world can that be. The phone is a piece of crap. They're
either going to fix these problems once and for all or give us our money back.<o:p></o:p></span></font></p>

I saw this topic and I myself the recommend the same!! Stay away from<br>
Grandstream... unless you are younger, much hair in the head and no<br>
white hair :-) <br>
