I am working on a FreePBX 18.104.22.168 system with the commercial Endpoint Manager and ~100 Yealink telephone handsets.
I need to add some common configuration settings for some Yealink phones. Normally (i.e. on a non-FreePBX based system), I would add common settings to the common configuration file (e.g. y0000000000xx.cfg). However, there is a note at the top of file warning “DO NOT HAND MODIFY THIS FILE!” and sure enough, modifications are overwritten when we update the FreePBX.
I am unable to find a way, either via the FreePBX Web Client or referenced in the documentation, to add settings to these common configuration files. Is there a way to do this ? If not, please could you advise best practice for specifying global configuration settings for all Yealink phones ?
