Nubie question: Configuring Grandstream GXP-2000 handsets

Our 20+ GXP-2000’s appear to be loading configuration files from our Asterisk server, invalidating whatever I enter into the local handset either directly via menu or through the web interface.

Case in point: We have a new employee. The old employee’s name appears on the handset LCD screen. Changing the name on the extension in FreePBX doesn’t help. Changing the name on the local handset is overwritten on reboot.

SO - where are these files on Asterisk? I simply need to get into whatever config files are being loaded and edit the needed information. Help!


Not enough information to answer your question.

Do you know how which protocol they use to get the configs? http, ftp, tftp?

The proper place to change a phones setup is in the config files that are loaded and not the phone handset. At work we use 45 Aastra phones and 2 Polycom Conference phones. Both are reset to factory defaults and we only change that absolute minimum needed on the phone. Polycom defaults to tftp which is great. Aastra defaults to tftp also. the only values I change in the phones directly are the settings for where it can do it vha http request so I set the website and directory path. Inside our building we use tftp but external they use http so when a phone goes external they use the interface to change that one value and they can go plug in anywhere (almost).

OK - so when a handset boots it displays “TFTP Provisioning” and then loads a couple of .bin files I’ve traced to a /Grandstream folder on the Asterisk server. However, perusing this folder, I find no magical file that contains all the configuration information. -bw

The files that contain the settings are in this folder and are in the format of ‘cfg’+mac-address. Example: cfg000B82010000, cfg000B82010001, cfg000B82010002.

To read about this feature please go to: and download the Configuration Tool Program, Configuration Template and User Guide.

Or you can just remove all cfg+mac-address files and set up the phones by using the web gui.

Just the tip I was looking for. Thanks!
