GXP 2000 Firmware 1.0.1.2
Greetings all
Grandstream released a new firmware and it seems like the speaker phone
problem has been fixed. However we updated to firmware
1.0.1.12<http://1.0.1.12>to fix the echo problem but found other
problems were now
created. The worst of these new problems is that the whole phone starts
degrading, the volume starts getting lower and lower. The ringing starts
fading and the calls

GXP-2000 fw 1.0.1.13 and NTP
Hi all
Slightly OT but I know a lot of GS experts hang out here - I just upgraded a
GXP-2000 to firmware 1.0.1.13 to try out the BLF functionality with Asterisk
(which so far works as expected), but as a side-effect the phone won't sync
with an NTP server - I've tried different server names (time.nist.gov and
pool.ntp.org) and IPs in the config, but it refuses to update the time on

GXP-2000 registration issues
Greetings all
I was wondering if any of you have found this problem. I have a setup with
80 GXP-2000s which work great until I decide to stop now my asterisk server.
When it comes back up half of the phones (not always the same ones) fail to
register with Asterisk. I set up the phones to register and send keep alives
(register every 4 minutes, send keep alives every 20 seconds) to no avail.

GXP-2000 Volume Issue
Is anyone else having an issue with GXP-2000s and transmit gain? All my
other phones are fine on my TDM400P with txgain set at 0, but the GXP-2000
caps at about a third of the scale in ztmonitor. I'm getting people
complaining they can't hear me on my GXP-2000s, whereas my Snom 320 and
Polycom 301 are great, and my Budgetones are overmodulating. Is there any
conceivable fix on the

GXP-2000 phones stop registering
I have about 30 GXP-2000 phones running 1.0.1.9 which have all been
configured using the provisioning feature so the configuration is all
identical.
The problem I am having is that they randomly seem to stop registering
with asterisk. When they stop registering they can still make calls but
oviously asterisk cannot ring the phone so all incoming calls go to
voicemail.

GXP-2000
I'm using a few GXP-2000 with firmware 1.0.2.13 and everything seems
to be working fine. However, there are a couple of issues I'd like to
know if are possible:
1) Even though the phone has 4 line appearances, if I am speaking on
a line, the phone can no longer receive phone calls. I can manually
select another line and make calls, but when Asterisk tries to send a
call to it, I

FYI, spoke with Grandstream this morning, the GXP-2000 release has been

GXP-21XX
Anyone used the new Grandstream GXP-21XX series phones. We have been
testing these phones and like what we see. We are looking for a greater
cross section of testing before we roll them to production. Any feed back
would be appreciated. We are talking with Grandstream engineering and they
are looking for feed back as well.
Any input is appreciated.
Thanks

GXP-2000 w/ 1.1.0.11 firmware
I had provisioning via tftp working on this phone. I have verified that
after the firmware upgrade, it contacts the tftp server and downloads
the cfgMACADDR file, and the ring/etc files successfully. Unfortunately,
changes made to the config file don't make it to the phone (SIP account
info/server info, etc).
The script that I am using to generate the binary files is loosely based

Problems if GXP-2000 phones and Asterisk are not on the same network
Hi,
I have a lot of GXP-2000 phones not registering with Asterisk server.
After two days of attempts, it seems that problem is due to the fact that
phones and server are not on the sme network.
Do you know if this is known issue?

GXP-2000 and Shared Line Appearances
I have a client with 20 GXP-2000s. Everything seems to be working
fine. However, after a couple of weeks of use, the client is having a
hard time adjusting to the new IP based phone systems and only misses
one feature from their old Lucent system.
That is, they had 8 analog lines before and all their old Lucent
phones showed a button for each line. So, it was easy for anyone to

Provisioning GXP 2000
I've done some googling and searched voip-info but I'm not able to find a
good answer about how to provision the GXP 2000.
Based on questions I've asked before it seems like a lot of people are using
the grandstream phones so I figure provisioning can't be that hard. Is
everyone using the web interface for *every* phone? Or is there a better,
more automatic, way?
TIA!!!
Thanks,

Feedback on Linksys SPA-921 and GrandStream GXP-2000
Hello
I'm about to order a GrandStream GXP-2000 and a Linksys SPA-921
I'd like to have some user feedback about how those phones perform, and
whether their LCD screen displays both the caller ID name and number (The
GrandStream BT-100 only displays numbers, which isn't very helpful).
Thank you.

How to do Automatic Daylight Saving on Grandstream GXP-2000
Hi,
I'd set the daylight saving option to yes on all the GXP-2000 phones, but
apparantly it doesn't move it an hour back on last sunday of October. So now
I am stuck will all the phones showing the wrong time. Isn't there an option
so that it'll automatically update daylight savings?
Thanks

GXP-2000 1.1.0.13 Issues
I have had 2 GXP-2000 for a while now and been slowly following the
firmware releases made by Grandstream and am now up to 1.1.0.13. This
version works really well on these 2 original phones (MAC's
00:0B:82:06:xx:xx), so I went ahead and ordered another 2 phones (MAC's
00:0B:82:09:xx:xx). One of these I upgraded to 1.1.0.13 (it came with
1.1.0.5) and pressed it into use.
