Upgrading Grandstream GXP2130 from 1.0.7.x to 1.0.11.x

2020-12-05 13:43:00

With many thanks to my friends at ITVitae and some dumpster diving I snagged two brand-new Grandstream GXP2130 IP phones, to practice VOIP in my homelab. They're pretty sexy phones! Nice build quality and a very decent admin interface: a great first step into the world of VOIP / SIP. 

Out of the box, these two phones came with the dated 1.0.7.25 firmware. No matter what I tried, they refused to upgrade to the current version 1.0.11.16. Pointing them at the Granstream firmware site? Nothing. Pointing them at a local web server with the 1.0.11.16 firmware? Nothing. 

After a bit of searching, I found a helpful thread on the GS support forums that suggests that the firmware version gap is simply too great. We need to apply a few of the in-between versions, one by one.

As a work-around I built my own firmware upgrade server, in the VOIP network segment of my homelab. A simple CentOS 7 box with Apache. I then did the following:

cd /tmp
wget http://www.grandstream.com/sites/default/files/Resources/RingTone.zip
wget http://firmware.grandstream.com/Release_GXP2130_1.0.7.97.zip 
wget http://firmware.grandstream.com/Release_GXP2130_1.0.8.56.zip 
wget http://firmware.grandstream.com/Release_GXP2130_1.0.9.135.zip 
wget http://firmware.grandstream.com/Release_GXP2130_1.0.11.3.zip 
wget http://firmware.grandstream.com/Release_GXP2130_1.0.11.16.zip 

unzip RingTone.zip
for FILE in $(ls Release*zip); do unzip $FILE; done

cd /var/www/html
sudo mkdir 7 8 9 11

sudo cp /tmp/ring* 7/; sudo cp /tmp/Rel*.7.*/*bin 7/
sudo cp /tmp/ring* 8/; sudo cp /tmp/Rel*.8.*/*bin 8/
sudo cp /tmp/ring* 9/; sudo cp /tmp/Rel*.9.*/*bin 9/
sudo cp /tmp/ring* 11/; sudo cp /tmp/Rel*.11.*/*bin 11/

sudo chmod -R o+r *

From there on out, run a "sudo tail -f /var/log/httpd/access.log" to see if the phone is actually attempting to pick up the relevant update files.

Then, on the phone, login as "admin" and browse to Maintenance > Upgrade and Provisioning. Set the access method to HTTP. As the Firmware Server Path set the IP address of the newly built upgrade server (e.g. 192.168.210.100), followed by the version path. We will change this path for every version upgrade.

For example:

First update to 1.0.7.97: set the path, click Save and Apply, then at the top click Provision. You should see the phone downloading the firmware update in "access.log". Once the phone has rebooted, check the web interface for the current version number.

Then "lather, rince and repeat" for each consecutive version. After 7, upgrade to 8, then to 9, then to 11 (this works without issues). In the end you will have a Grandstream phone running 1.0.11.16, after starting at 1.0.7.25.

Afterwards: don't forget to reset the phone to factory defaults, so it will correctly join your PBX for auto-provisioning.
