The location used to store template files depends on the type of IP Office system.
IP500 V2 - IP Office Manager export templates to a \manager_files\template sub-folder of the directory where it is installed.
Linux-based systems - Templates are stored on the Primary Server. When the system configuration is opened by IP Office Manager, those templates are downloaded from server to the \manager_files\template folder. When the configuration is saved, the templates are uploaded back to server.
Caution:
If you are using IP Office Manager to manage both IP500 V2 and Linux-based IP Office systems, you need to ensure that you store the IP500 V2 templates in a directory other than the default directory before opening any Linux-based system configuration. When doing so, existing template in the \manager_files\template folder may be overwritten.
