<DIV><FONT face=Arial size=2>The Grandstream speakerphone is just about useless
to me. I have a problem with their VOX not working right and if you try to
mute a conference, the phone hangs up in a random period of time. I
contacted their tech support and got this message from them:</FONT></DIV>

<DIV><FONT face=Arial><EM>Dear Joe McConnaughey,<BR><BR>Thank you for your
email. <BR><BR>Yes, we are aware these two bugs and engineering is working on
that. <BR>The mute one is easy to fix but the echo (AEC) is not so easy to fix,
but we are working on that and you should be able to get the fix
soon.<BR><BR>Thanks.<BR><BR><BR><BR>Best Regards,<BR>John Huang <BR>Grandstream

text/plain; charset="US-ASCII"<BR><BR>I have a really baffling problem.<BR><BR>A
couple of months ago I purchased a pair of GrandStream GSX-2000 phones
for<BR>use with Asterisk.<BR><BR>At first all was well. But recently I've
noticed terrible sound quality<BR>problems. Basically the sound will "glitch" or
stutter randomly from time to<BR>time.<BR><BR>Now, what is interesting is that
this happens even with the phone totally<BR>disconnected from any network. You
can hear it on the dial-tone that the<BR>phone itself generates if you press
SPEAKER or lift the handset, with no<BR>network cable plugged in. So whatever is
causing this glitching would seem<BR>to be being generated within the phone
itself, and not coming from an<BR>external source. (It isn't the power, as the
two phones are in different<BR>buildings in different towns. Besides, both are
connected to UPSs).<BR><BR>To me this seems to indicate a fault with the phones
themselves. But for<BR>both of them to develop the same fault at the same time
seems odd. <BR><BR>I asked on the voipuser.org forum if anybody else had had
similar problems,<BR>but everybody who responded said all was well with their
phones.<BR><BR>But given the wider reach of this list, I thought I'd ask here as
well.<BR><BR>Both phones have the latest firmware from the GS
website.<BR><BR>Does anyone have any ideas? Has anyone had anything similar
happen to them?<BR><BR>Faris.<BR><BR>p.s. This is my first post here. Please be
gentle with me :-)<BR><BR></DIV></BODY></HTML>
