3CX Custom Provisioning Templates

If you want to provision unsupported phones to use with 3CX, you may come across this article on the 3CX web site:  Provisioning unsupported IP phones. It looks quite helpful but it’s out of date in an important area:  the location of the templates.

Looks to me like the simplest and safest approach is to use the web UI for customizations, but it’s still helpful to know where the files are stored.
