Post your experiences here:

  • Major : BEWARE !!! From 7 Grandstream phones, which I flashed with the new 1.1.6.44 firmware, 4 of them hang and didn't reboot, the next thing I got was a blank screen, after I unplugged them after 2 hours. These were 3 GXP-2000 and one GXP-2010. Now the only chance to restore them is to ship them to the Grandstream factory.
  • Major : I cannot upgrade. In syslog I see: ERROR 4108 GET boot55e.bin and ERROR 4108 GET gxp2000e.bin The phone is now dead. All the leds stay lit. The only way to boot is to power on with ethernet cable unplugged, but everytime I call a number the phone reboots. (HV 0.4)
  • Major : There also seems to be a problem with version 1.1.6.44 regarding transfering calls using the speed dial buttons. In short, they don't work. I have down-graded my GXP2000s (HW 1.1A) to version 1.1.6.16, which seems to be stable.
  • Minor : GXP2000 (HW 0.4), FW version 1.1.6.44. I tried it to see if it would brick and to see if I could get one of the new features working (send DTMF during the communication state). After downloading and installing, it does not brick but phone shows 1.1.6.37. Is this because HW 0.4 must stick with FW 37? - ampster
  • Minor : GXP2010 and 2020. Call waiting tone volume cannot be heard, its volume is too low and cannot be heard during a normal voice call and there is no way to raise its volume - AgX
  • Major : GXP2010 under heavy call load will stop working almost 2 times everyday. Into the syslog there are a lot of "out of memory" errors reported by the phones. Them will also fail to re-register with the PBX and BLF button will also stop working. Outgoing calls are luckly still possible. The phones will also unable to re-subscribe BLF if asterisk service will be restarted, in that case, a Call/Leg Transcation error is reported everytime the phone tries to resubscribe. Only rebooting the phones fixes the problems. - AgX
  • Minor : GXP2000 (HW 2.2A), FW version 1.1.6.44/46. BLF lights are not consistent with Asterisk 1.4.2.22 (Elastix 1.5 beta), working for a few minutes and then becoming unreliable. I have fixed this by modifying Asterisk's chan_sip.c. The <dialog-info> contains an attribute called "version" which is supposed to increase at each message as per the RFC. With the GXP2000.... well, I have removed the ++ at the end of the p->dialogver variable (thus not increasing it) and that fixed the problem with the consistency of BLF. All the lights show up as they shold, no missed light so far, but the version attribute is always 0. I have informed Grandstream about it but no reply yet. I have also managed to modify asterisk to simulate OnHold blinking using DEVSTATE. - ady624

Post your experiences here:

  • Major : Either I'm retarded or the firmware update is missing for the GXP2000. Unzipped Release_BT200_GXP_1.1.6.37.zip (The file for GXP2000 according to the firmware download site) and the gxp2000*.bin files have modification dates in 2007. Additionally with the phone set for always check for new firmware on boot it does not see a new revision above current 1.1.6.16. I tried both a local TFTP server and the Grandstream on multiple phones?? HW1.1 and 0.4 -p
  • Major : I've the same problem: I can't upgrade because the phone looks for a file named gxp2000e.bin that's not in the archive. HV 1.1A
  • Comment : Sorry, I don't understand what's gone wrong for you. I downloaded the package from the Grandstream site, and it DOES contain gxp2000e.bin (NOT gxp200e.bin - no such file required, despite previous comment) dated 10-15-2008. My GXP2000s upgraded just fine, but most (all?) of the BT200s required a manual power-cycle (unplug power - wait a few secs - plug back in) after they attempted the upgrade.
  • Major : I'm sorry for the type (corrected), I really meant gxp2000e.bin. Anyway I can assure you that that file is NOT present in the archive, here is the complete list of files:
boot55a.bin boot55c.bin boot55e.bin bt200e.bin gxp2000a.bin gxp2000d.bin gxp2020d.bin ring3.bin boot55b.bin boot55d.bin bt200c.bin gxp1200d.bin gxp2000b.bin gxp2010d.bin gxp2020e.bin ring1.bin boot55.bin boot55e16.bin bt200d.bin gxp1200e.bin gxp2000c.bin gxp2010e.bin gxp280e.bin ring2.bin
and as you can see there are bt200e.bin, gxp1200e.bin, gxp2010e.bin, gxp2020e.bin, gxp280e.bin but no gxp2000e.bin.
  • Comment : Isn't that interesting? The archive I downloaded a week ago is 13,635 Kbytes, and contains the file in question; the zip file - of the same name as the one I got last week - now on the Grandstream website is only 12K bytes, and does NOT contain gxp2000e.bin, as you rightly say. Perhaps Grandstream corrected something in the original, but then stuffed up by leaving this file out when they re-posted it. Something like that, anyway. Oh, they do try one's patience!
  • Major : I have had a reply from Grandstream:
"Thanks for your email. But we take the files for GXP2000 to upgrade since we find a bug in that firmware. We will release a fix pretty soon."
So gxp2000e was deliberately removed from the archive because of a bug. We'll just have to be patient ...

Post your experiences here:
  • Minor: Language Packs in the GXP2020 doesn't resolve the accent problem in Italian Language- lfelicetti
  • Intermediate : If i put P342=1 on TFTP provisoning Config the phone goes in an infinite reboot loop cycle. Removing P342 or setting it to 0 resolve the issue, but can't change language on phone. Any Suggestion? - lfelicetti
    • Try this Solution: Try to set P342=2. Works for me. - lfelicetti
  • Major : After picking up a call using the gxp-2000's "Busy Lamp Feature", a subsequent transfer of this call will fail (under asterisk). This is due to the gxp-2000 incorrectly leaving the "replaces" header from the initial pickup in the sip re-invite to put the call on hold as the transfer takes place.
  • Intermediate : Setting a Mutipurpose key to "Speed Dial"/"Account2"/<number> tries to make the call using Account 1 - Linker3000
  • Minor : Accents in language packs don't work in the menu - Snipe Foo
    • confirmed: the italian language pack is unusable, all accents are with strange characters. For example the days of the week are full of errors. And i think is not a minor bug, but a mayor. The first thing that a user look on a idle phone is the display...- francesco_r
      • resolved: the last language pack available in http://www.grandstream.com/DOWNLOAD/FIRMWARE/BT200_GXP1200_GXP2000_GXP2010_GXP2020/Language_Pack.zip correct this issue. - francesco_r
      • resolved: the last language pack corrected the issue for French too. For me it was a minor bug because users could still use English language, as they did for almost 3 years...- Snipe Foo
  • Major : If i stop and restart the asterisk server, the BLF subscriptions are not update after the registration period. I must also reboot all the phones to make BLFs work again.- francesco_r
    • The comment above is not true, obiovusly this user does not how to configure asterisk and this phone...- AntonioGallo
      • Antonio you are wrong. I have retested and i can confirm this bug, but -only- with Asterisk 1.4.19. 1.4.18.1 instead works well. So there is an incompatibility with asterisk 1.4.19. Other phones, like Aastra, Snom and Thomson on the same server with asterisk 1.4.19 works well. Also GXP2000 with version 1.1.4.18 and asterisk 1.4.19 works well, so there is something wrong with this release. - francesco_r
      • UPDATE 19/04/2008: the BLF get lost after some days without the asterisk restart. And the Asterisk version is not relevant. If i enable a sip debug in the log i can see "481 Call/Transaction Does Not Exist". Phones with version 1.1.5.15 are not affected by this bug. Also other users not using asterisk have the same problem: http://www.3cx.com/forums/gxp-2020-blf---bug-in-firmware-4929.html . - francesco_r
        • resolved: i have installed the unofficial release 1.1.6.22 and no more issues with BLF. - francesco_r
        • unresolved: with Release_1.1.6.27.zip I still have problem, I have 28 gxp-2000 (8 with extension) and random some led stop to work: I see the green status, the blinking status, but when I see the "inuse" message on asterisk console the status led on the gxp-2000 with extension return to green; the same problem does not happen on the 7 integrated led but only on the extension; the extension ship with the patch to the gxp-2000 and with the power-supply, since I notice that the patch give the power to the extension I didn't use the power supply, I must use it anyway? - andrea_n
  • Minor : Having occasional sound blackuots 5-10 seconds one way or two way (not sure yet if both) and also more than normal cut off calls. Suspect sound cut off only (RTP stream something). I would like to downgrade back to 1.1.4.14 which has worked well (HW1.1A) but when trying, the phone requests boot55e.bin which is not there in the previous release. Haven't had the guts to just copy that file over (from 1.1.6.16) as I can't afford to brick my phone...- Carlottoo
    • Update: I haven't had any cut off calls for a while, but the blackouts are there. I can't hear the other party for about 5 secs, i think they can hear me in most cases. I might have hung up in the past believing the call was cut off. Doesn't happen that often so I can live with it for now...-
    • I've noticed that setting type=peer and qualify=no seems to help - Pennywell
  • Major : A 16 months old GXP2000 phone stopped to work after upgrading to this firmware. Now the phone is locked into a constant rebooting, sometimes it start up but when you connect it with the PC cable it start rebooting again. Most recent phones are working perfectly and we're moving all the phones to this firmware soon. - AntonioGallo
    • I had the same issue with about half of my phones, but you can stop the rebooting cycle after the firmware has been applied and uploaded by disconnecting the phones for about 30 seconds. The phone normally seems to perform the update in two parts, so at a minimum the phone should restart twice before this will work. Since then I haven't had any major issues with them yet. - Carmen
  • Comment: This firmware rocks. After waiting impatiently for years all of my problems (even the minor ones) from previous firmwares seem to be gone. HV 1.1A. -p
  • Minor : If I set the default callerid in sip.conf to something with a space in it (such as callerid=CallerID Unavailable) then call a GXP-2000 from the Asterisk console, the GXP-2000 cannot transfer the call. If I remove the space (such as callerid=Unavailable) the same call transfers fine. I have tried both dialling the destination extension manually and using the BLF keys - same problem. - drew_w
  • Minor : As in version 1.1.5.* there is some MTU problem and I can't access phones via VPN (OpenVPN). Older releases worked fine. Error in OpenVPN log is '"write UDPv4 [EMSGSIZE Path-MTU=1500]: Message too long (code=90)"' - Dusty
  • Minor : French language pack contain a lot of wrong words. For example : "Bottin" should be "Annuaire" and "Nouvel entrée" should be "Nouvelle entrée". - Snipe Foo
  • Comment: This firmware really rocks. I've been following Grandstream firmware developpement since a long time and after waiting impatiently for years all of my problems (even the minor ones) from previous firmwares seem to be gone.
  • Minor :Early dial does not work with asterisk 1.2.13 with GXP-2000 (HV 0.4A) and GXP-2020 (HV 0.2C) on 1.1.6.16 firmware
  • Minor : If phonebook exeedes 16kB, sh*t happends. Confirmed by Grandstream. Suggested workaround: Delete some entrys - Bad2Dbone
  • Major : A 2 year old GXP2000 phone reboots every time I hit the MSG key (code *1) after upgrading to this firmware. If I dial *1 then the mailbox is accessed correctly. Reducing the XML phonebook size to about 8k didn't make any difference. - adw

Instructions to Upgrade a GXP-2000 to Firmware version 1.0.2.3 using Linux - gammacoder


Watch out for upgrading via HTTP. Although it worked for me, I've heard of a continual reboot loop until the .bin files are removed from the HTTP server. I've had success upgrading via TFTP following these steps:

  • On your Linux Box (Make sure you have a tftp server installed, the package for Fedora/Redhat is 'tftp-server')
    • cd /tftpboot (or your tftp server root directory)
    • wget http://www.grandstream.com/BETATEST/GXP2000/Release_1.0.2.3_GXP2000.zip
    • unzip Release_1.0.2.3_GXP2000.zip
    • /usr/sbin/tcpdump port tftp (to watch tftp requests from the phone)

  • Point your webserver to http://ip.add.dr.ess from the phone's front panel
    • Login with the administrator password
    • Advanced Settings: set Firmware Upgrade: Via TFTP Server and set the IP address to your TFTP server
    • Click Update
    • Click Reboot

  • Watch tcpdump, you'll see requests for
    • boot55.bin
      • If it hangs here for more than 10 seconds, pull power and reboot.
      • On the phone's Web Interface, under Status, you'll have Bootloader-- 1.97.1.99
      • Reboot the phone from the web interface one more time
    • boot55a.bin
    • boot55a.bin (again)
    • gxp2000a.bin
    • cfgxxxxxxxxxxxx (where xxxxxxxxxxxx is the MAC address)
    • cfg.txt

  • The phone boots up, then runs through the new provisioning code. In tcpdump, you'll see:o
    • cfgxxxxxxxxxxxx (again)
    • boot55a.bin
    • gxp2000a.bin
    • ring1.bin
    • ring2.bin
    • ring3.bin



GXP-2000 central updating TFTP server (GXP-2000 firmware v1.0.1.9)


  • The first time you have to enter the TFTP server-IP in your phone through the web interface, as of then it will always look for the cfg file on the TFTP server.
  • On grandstream.com you find the Configuration Tool, you need this to convert the config file to the correct format. A config template can be found on that page also.
  • My cfg file is called cfg<mac-addr> and is placed in the tftp dir. If you have multiple phones, you need multiple cfg files.
  • Here is what I have changed from the default template:

  1. SIP Server
P47 = <SIP-server-IP>
  1. SIP User ID (200 is used as an example!)

P35 = 200
  1. Authentication ID


P36 = 200
  1. Authentication password

P34 = 200
  1. NAT Traversal. 0 - yes, 1 - no
P52 = 1
  1. TFTP Server (for remote software upgrade and configuration)
  2. For firmware version 1.0.5.22 and above)
  3. P213 =
  4. make sure you choose the next one:
  5. TFTP Server (for remote software upgrade and configuration)
  6. For firmware version below 1.0.5.22)
P41 = <TFTP-server-IP>
  1. "Account Name" in the webinterface for the 1st account
P270 = My Account Name
  1. SIP Registration. 0 - no, 1 - yes
P31 = 1
  1. Unregister On Reboot. 0 - no, 1 - yes
P81 = 1
  1. NTP Server
P30 = <NTP-server-IP>
  1. Time Zone. Offset in minutes to GMT (780 = brussels/paris/..)
P64 = 780
  1. Daylight Savings Time. 0 - no, 1 - yes
P75 = 1
  1. User Caller Name (John Doe)
P3 = Firstname
  1. Send DTMF. 0 - in audio 1 - via RTP 2 - via SIP INFO | set to 2 for Grandstream!
P73 = 2

  • After creating your config file, you need to convert it with the Configuration Tool and make them available on your TFTP server. (filename syntax: cfg000b8201XXXX)

Configuration Files Generator Tool for WINDOWS http://sourceforge.net/projects/provisioning/

The generator tool may create encrypted files. If you should need to convert these back into readable files, use this perl script:

In case it should be of any use to anybody, here's a perl implementation of the config file generation:

Update and Modify a GXP-2000 from the command line


(Jun/06), there is a sourceforge web site
http://handhelds.freshmeat.net/projects/gsutil/
which contains a perl script for manipulating all aspects of a GXP-2000 phone from the command line
knowing only the phone IP number. It is relatively easy to change the perl script as the firmware is upgraded.

Modifying the script

  • Here is a modified perl script gsutil.txt that I believe works with firmware up to and including 1.1.0.16. It has a .txt ending since the wiki does not accept .pl
    Image

  • (Jul 19/06) It works with 1.1.1.7 also but does not have the new bells and whistles for the extension unit, or some info to make adjusted parameters such as BLF presence work.

  • (Jul 26/06) Here is a modified gsutil.txt with the added info needed for the extension unit and firmware 1.1.1.7
    Image

Configuring the GXP-2000

To use the perl script in conjunction with the configuration template, you can use
a shell script such as:
Image

and an edited template file such as
Image

The command to generate a configuration file for an extension is then:

/bin/bash genxxx.txt XXX

where XXX is the extension number. It is assumed that the extension number is the same
as the last numeric part of the ip number.

The edited template file uses an asterisk server ip of 192.168.0.199
and a router ip of 192.168.0.15. You may change to suit your taste.

Configuration template files

Configuration template files for:

  • Firmware Version 1.1.1.7
    Image
    -ninthclowd

  • Firmware Version 1.0.1.12
    Image

  • Firmware Version 1.0.2.13
    Image

  • These were emailed to me directly from Grandstream some months ago. Others may find these useful.

  • I would really like to make each of the firmware version configuration templates files available here, but I do not have them. Can anyone provide more?

- Anthony

Post your experiences here:

  • Major : BEWARE !!! From 7 Grandstream phones, which I flashed with the new 1.1.6.44 firmware, 4 of them hang and didn't reboot, the next thing I got was a blank screen, after I unplugged them after 2 hours. These were 3 GXP-2000 and one GXP-2010. Now the only chance to restore them is to ship them to the Grandstream factory.
  • Major : I cannot upgrade. In syslog I see: ERROR 4108 GET boot55e.bin and ERROR 4108 GET gxp2000e.bin The phone is now dead. All the leds stay lit. The only way to boot is to power on with ethernet cable unplugged, but everytime I call a number the phone reboots. (HV 0.4)
  • Major : There also seems to be a problem with version 1.1.6.44 regarding transfering calls using the speed dial buttons. In short, they don't work. I have down-graded my GXP2000s (HW 1.1A) to version 1.1.6.16, which seems to be stable.
  • Minor : GXP2000 (HW 0.4), FW version 1.1.6.44. I tried it to see if it would brick and to see if I could get one of the new features working (send DTMF during the communication state). After downloading and installing, it does not brick but phone shows 1.1.6.37. Is this because HW 0.4 must stick with FW 37? - ampster
  • Minor : GXP2010 and 2020. Call waiting tone volume cannot be heard, its volume is too low and cannot be heard during a normal voice call and there is no way to raise its volume - AgX
  • Major : GXP2010 under heavy call load will stop working almost 2 times everyday. Into the syslog there are a lot of "out of memory" errors reported by the phones. Them will also fail to re-register with the PBX and BLF button will also stop working. Outgoing calls are luckly still possible. The phones will also unable to re-subscribe BLF if asterisk service will be restarted, in that case, a Call/Leg Transcation error is reported everytime the phone tries to resubscribe. Only rebooting the phones fixes the problems. - AgX
  • Minor : GXP2000 (HW 2.2A), FW version 1.1.6.44/46. BLF lights are not consistent with Asterisk 1.4.2.22 (Elastix 1.5 beta), working for a few minutes and then becoming unreliable. I have fixed this by modifying Asterisk's chan_sip.c. The <dialog-info> contains an attribute called "version" which is supposed to increase at each message as per the RFC. With the GXP2000.... well, I have removed the ++ at the end of the p->dialogver variable (thus not increasing it) and that fixed the problem with the consistency of BLF. All the lights show up as they shold, no missed light so far, but the version attribute is always 0. I have informed Grandstream about it but no reply yet. I have also managed to modify asterisk to simulate OnHold blinking using DEVSTATE. - ady624

Post your experiences here:

  • Major : Either I'm retarded or the firmware update is missing for the GXP2000. Unzipped Release_BT200_GXP_1.1.6.37.zip (The file for GXP2000 according to the firmware download site) and the gxp2000*.bin files have modification dates in 2007. Additionally with the phone set for always check for new firmware on boot it does not see a new revision above current 1.1.6.16. I tried both a local TFTP server and the Grandstream on multiple phones?? HW1.1 and 0.4 -p
  • Major : I've the same problem: I can't upgrade because the phone looks for a file named gxp2000e.bin that's not in the archive. HV 1.1A
  • Comment : Sorry, I don't understand what's gone wrong for you. I downloaded the package from the Grandstream site, and it DOES contain gxp2000e.bin (NOT gxp200e.bin - no such file required, despite previous comment) dated 10-15-2008. My GXP2000s upgraded just fine, but most (all?) of the BT200s required a manual power-cycle (unplug power - wait a few secs - plug back in) after they attempted the upgrade.
  • Major : I'm sorry for the type (corrected), I really meant gxp2000e.bin. Anyway I can assure you that that file is NOT present in the archive, here is the complete list of files:
boot55a.bin boot55c.bin boot55e.bin bt200e.bin gxp2000a.bin gxp2000d.bin gxp2020d.bin ring3.bin boot55b.bin boot55d.bin bt200c.bin gxp1200d.bin gxp2000b.bin gxp2010d.bin gxp2020e.bin ring1.bin boot55.bin boot55e16.bin bt200d.bin gxp1200e.bin gxp2000c.bin gxp2010e.bin gxp280e.bin ring2.bin
and as you can see there are bt200e.bin, gxp1200e.bin, gxp2010e.bin, gxp2020e.bin, gxp280e.bin but no gxp2000e.bin.
  • Comment : Isn't that interesting? The archive I downloaded a week ago is 13,635 Kbytes, and contains the file in question; the zip file - of the same name as the one I got last week - now on the Grandstream website is only 12K bytes, and does NOT contain gxp2000e.bin, as you rightly say. Perhaps Grandstream corrected something in the original, but then stuffed up by leaving this file out when they re-posted it. Something like that, anyway. Oh, they do try one's patience!
  • Major : I have had a reply from Grandstream:
"Thanks for your email. But we take the files for GXP2000 to upgrade since we find a bug in that firmware. We will release a fix pretty soon."
So gxp2000e was deliberately removed from the archive because of a bug. We'll just have to be patient ...

Post your experiences here:
  • Minor: Language Packs in the GXP2020 doesn't resolve the accent problem in Italian Language- lfelicetti
  • Intermediate : If i put P342=1 on TFTP provisoning Config the phone goes in an infinite reboot loop cycle. Removing P342 or setting it to 0 resolve the issue, but can't change language on phone. Any Suggestion? - lfelicetti
    • Try this Solution: Try to set P342=2. Works for me. - lfelicetti
  • Major : After picking up a call using the gxp-2000's "Busy Lamp Feature", a subsequent transfer of this call will fail (under asterisk). This is due to the gxp-2000 incorrectly leaving the "replaces" header from the initial pickup in the sip re-invite to put the call on hold as the transfer takes place.
  • Intermediate : Setting a Mutipurpose key to "Speed Dial"/"Account2"/<number> tries to make the call using Account 1 - Linker3000
  • Minor : Accents in language packs don't work in the menu - Snipe Foo
    • confirmed: the italian language pack is unusable, all accents are with strange characters. For example the days of the week are full of errors. And i think is not a minor bug, but a mayor. The first thing that a user look on a idle phone is the display...- francesco_r
      • resolved: the last language pack available in http://www.grandstream.com/DOWNLOAD/FIRMWARE/BT200_GXP1200_GXP2000_GXP2010_GXP2020/Language_Pack.zip correct this issue. - francesco_r
      • resolved: the last language pack corrected the issue for French too. For me it was a minor bug because users could still use English language, as they did for almost 3 years...- Snipe Foo
  • Major : If i stop and restart the asterisk server, the BLF subscriptions are not update after the registration period. I must also reboot all the phones to make BLFs work again.- francesco_r
    • The comment above is not true, obiovusly this user does not how to configure asterisk and this phone...- AntonioGallo
      • Antonio you are wrong. I have retested and i can confirm this bug, but -only- with Asterisk 1.4.19. 1.4.18.1 instead works well. So there is an incompatibility with asterisk 1.4.19. Other phones, like Aastra, Snom and Thomson on the same server with asterisk 1.4.19 works well. Also GXP2000 with version 1.1.4.18 and asterisk 1.4.19 works well, so there is something wrong with this release. - francesco_r
      • UPDATE 19/04/2008: the BLF get lost after some days without the asterisk restart. And the Asterisk version is not relevant. If i enable a sip debug in the log i can see "481 Call/Transaction Does Not Exist". Phones with version 1.1.5.15 are not affected by this bug. Also other users not using asterisk have the same problem: http://www.3cx.com/forums/gxp-2020-blf---bug-in-firmware-4929.html . - francesco_r
        • resolved: i have installed the unofficial release 1.1.6.22 and no more issues with BLF. - francesco_r
        • unresolved: with Release_1.1.6.27.zip I still have problem, I have 28 gxp-2000 (8 with extension) and random some led stop to work: I see the green status, the blinking status, but when I see the "inuse" message on asterisk console the status led on the gxp-2000 with extension return to green; the same problem does not happen on the 7 integrated led but only on the extension; the extension ship with the patch to the gxp-2000 and with the power-supply, since I notice that the patch give the power to the extension I didn't use the power supply, I must use it anyway? - andrea_n
  • Minor : Having occasional sound blackuots 5-10 seconds one way or two way (not sure yet if both) and also more than normal cut off calls. Suspect sound cut off only (RTP stream something). I would like to downgrade back to 1.1.4.14 which has worked well (HW1.1A) but when trying, the phone requests boot55e.bin which is not there in the previous release. Haven't had the guts to just copy that file over (from 1.1.6.16) as I can't afford to brick my phone...- Carlottoo
    • Update: I haven't had any cut off calls for a while, but the blackouts are there. I can't hear the other party for about 5 secs, i think they can hear me in most cases. I might have hung up in the past believing the call was cut off. Doesn't happen that often so I can live with it for now...-
    • I've noticed that setting type=peer and qualify=no seems to help - Pennywell
  • Major : A 16 months old GXP2000 phone stopped to work after upgrading to this firmware. Now the phone is locked into a constant rebooting, sometimes it start up but when you connect it with the PC cable it start rebooting again. Most recent phones are working perfectly and we're moving all the phones to this firmware soon. - AntonioGallo
    • I had the same issue with about half of my phones, but you can stop the rebooting cycle after the firmware has been applied and uploaded by disconnecting the phones for about 30 seconds. The phone normally seems to perform the update in two parts, so at a minimum the phone should restart twice before this will work. Since then I haven't had any major issues with them yet. - Carmen
  • Comment: This firmware rocks. After waiting impatiently for years all of my problems (even the minor ones) from previous firmwares seem to be gone. HV 1.1A. -p
  • Minor : If I set the default callerid in sip.conf to something with a space in it (such as callerid=CallerID Unavailable) then call a GXP-2000 from the Asterisk console, the GXP-2000 cannot transfer the call. If I remove the space (such as callerid=Unavailable) the same call transfers fine. I have tried both dialling the destination extension manually and using the BLF keys - same problem. - drew_w
  • Minor : As in version 1.1.5.* there is some MTU problem and I can't access phones via VPN (OpenVPN). Older releases worked fine. Error in OpenVPN log is '"write UDPv4 [EMSGSIZE Path-MTU=1500]: Message too long (code=90)"' - Dusty
  • Minor : French language pack contain a lot of wrong words. For example : "Bottin" should be "Annuaire" and "Nouvel entrée" should be "Nouvelle entrée". - Snipe Foo
  • Comment: This firmware really rocks. I've been following Grandstream firmware developpement since a long time and after waiting impatiently for years all of my problems (even the minor ones) from previous firmwares seem to be gone.
  • Minor :Early dial does not work with asterisk 1.2.13 with GXP-2000 (HV 0.4A) and GXP-2020 (HV 0.2C) on 1.1.6.16 firmware
  • Minor : If phonebook exeedes 16kB, sh*t happends. Confirmed by Grandstream. Suggested workaround: Delete some entrys - Bad2Dbone
  • Major : A 2 year old GXP2000 phone reboots every time I hit the MSG key (code *1) after upgrading to this firmware. If I dial *1 then the mailbox is accessed correctly. Reducing the XML phonebook size to about 8k didn't make any difference. - adw

Instructions to Upgrade a GXP-2000 to Firmware version 1.0.2.3 using Linux - gammacoder


Watch out for upgrading via HTTP. Although it worked for me, I've heard of a continual reboot loop until the .bin files are removed from the HTTP server. I've had success upgrading via TFTP following these steps:

  • On your Linux Box (Make sure you have a tftp server installed, the package for Fedora/Redhat is 'tftp-server')
    • cd /tftpboot (or your tftp server root directory)
    • wget http://www.grandstream.com/BETATEST/GXP2000/Release_1.0.2.3_GXP2000.zip
    • unzip Release_1.0.2.3_GXP2000.zip
    • /usr/sbin/tcpdump port tftp (to watch tftp requests from the phone)

  • Point your webserver to http://ip.add.dr.ess from the phone's front panel
    • Login with the administrator password
    • Advanced Settings: set Firmware Upgrade: Via TFTP Server and set the IP address to your TFTP server
    • Click Update
    • Click Reboot

  • Watch tcpdump, you'll see requests for
    • boot55.bin
      • If it hangs here for more than 10 seconds, pull power and reboot.
      • On the phone's Web Interface, under Status, you'll have Bootloader-- 1.97.1.99
      • Reboot the phone from the web interface one more time
    • boot55a.bin
    • boot55a.bin (again)
    • gxp2000a.bin
    • cfgxxxxxxxxxxxx (where xxxxxxxxxxxx is the MAC address)
    • cfg.txt

  • The phone boots up, then runs through the new provisioning code. In tcpdump, you'll see:o
    • cfgxxxxxxxxxxxx (again)
    • boot55a.bin
    • gxp2000a.bin
    • ring1.bin
    • ring2.bin
    • ring3.bin



GXP-2000 central updating TFTP server (GXP-2000 firmware v1.0.1.9)


  • The first time you have to enter the TFTP server-IP in your phone through the web interface, as of then it will always look for the cfg file on the TFTP server.
  • On grandstream.com you find the Configuration Tool, you need this to convert the config file to the correct format. A config template can be found on that page also.
  • My cfg file is called cfg<mac-addr> and is placed in the tftp dir. If you have multiple phones, you need multiple cfg files.
  • Here is what I have changed from the default template:

  1. SIP Server
P47 = <SIP-server-IP>
  1. SIP User ID (200 is used as an example!)

P35 = 200
  1. Authentication ID


P36 = 200
  1. Authentication password

P34 = 200
  1. NAT Traversal. 0 - yes, 1 - no
P52 = 1
  1. TFTP Server (for remote software upgrade and configuration)
  2. For firmware version 1.0.5.22 and above)
  3. P213 =
  4. make sure you choose the next one:
  5. TFTP Server (for remote software upgrade and configuration)
  6. For firmware version below 1.0.5.22)
P41 = <TFTP-server-IP>
  1. "Account Name" in the webinterface for the 1st account
P270 = My Account Name
  1. SIP Registration. 0 - no, 1 - yes
P31 = 1
  1. Unregister On Reboot. 0 - no, 1 - yes
P81 = 1
  1. NTP Server
P30 = <NTP-server-IP>
  1. Time Zone. Offset in minutes to GMT (780 = brussels/paris/..)
P64 = 780
  1. Daylight Savings Time. 0 - no, 1 - yes
P75 = 1
  1. User Caller Name (John Doe)
P3 = Firstname
  1. Send DTMF. 0 - in audio 1 - via RTP 2 - via SIP INFO | set to 2 for Grandstream!
P73 = 2

  • After creating your config file, you need to convert it with the Configuration Tool and make them available on your TFTP server. (filename syntax: cfg000b8201XXXX)

Configuration Files Generator Tool for WINDOWS http://sourceforge.net/projects/provisioning/

The generator tool may create encrypted files. If you should need to convert these back into readable files, use this perl script:

In case it should be of any use to anybody, here's a perl implementation of the config file generation:

Update and Modify a GXP-2000 from the command line


(Jun/06), there is a sourceforge web site
http://handhelds.freshmeat.net/projects/gsutil/
which contains a perl script for manipulating all aspects of a GXP-2000 phone from the command line
knowing only the phone IP number. It is relatively easy to change the perl script as the firmware is upgraded.

Modifying the script

  • Here is a modified perl script gsutil.txt that I believe works with firmware up to and including 1.1.0.16. It has a .txt ending since the wiki does not accept .pl
    Image

  • (Jul 19/06) It works with 1.1.1.7 also but does not have the new bells and whistles for the extension unit, or some info to make adjusted parameters such as BLF presence work.

  • (Jul 26/06) Here is a modified gsutil.txt with the added info needed for the extension unit and firmware 1.1.1.7
    Image

Configuring the GXP-2000

To use the perl script in conjunction with the configuration template, you can use
a shell script such as:
Image

and an edited template file such as
Image

The command to generate a configuration file for an extension is then:

/bin/bash genxxx.txt XXX

where XXX is the extension number. It is assumed that the extension number is the same
as the last numeric part of the ip number.

The edited template file uses an asterisk server ip of 192.168.0.199
and a router ip of 192.168.0.15. You may change to suit your taste.

Configuration template files

Configuration template files for:

  • Firmware Version 1.1.1.7
    Image
    -ninthclowd

  • Firmware Version 1.0.1.12
    Image

  • Firmware Version 1.0.2.13
    Image

  • These were emailed to me directly from Grandstream some months ago. Others may find these useful.

  • I would really like to make each of the firmware version configuration templates files available here, but I do not have them. Can anyone provide more?

- Anthony
