The firmware update of the following devices can be done via:

Device web-interface

• Maxwell
• N670/N870

Changing the Maxwell auto-provisioning template.

First you would need to change the gigasetmaxwell.ph.xml provisioning template see this wiki article how to access the template.

Open the template and search for:

<provisioning version="1.1" productID="mx3b">

<!--
<firmware>
    <file version="2.25.6" url="%%PROVLINK%%/firmware/gigaset/GC_MAX_2.25.6-release.bin"/>
</firmware> -->

Change the template according to the wiki article. You can set the URL to your own server or upload the Gigaset software into the 3CX firmware directory.

• Remove the <!-- and -->
• Change the URL
• Change the version to the software version you want to use

<provisioning version="1.1" productID="mx3b">

<firmware>
    <file version="2.25.6" url="<SERVER URL>/firmware/%DVID/GC_MAX_2.25.6-release.bin"/>
