    • and Rebuild Configs- This will save your changes to the PBX Database and will also write out new config file for the phones that are using this template as mapped in Extension Mapping section of End Pint Manager but the phones will need to be rebooted for it to retrieve the changes.
    • and Force Update- Will do both the Rebuild Configs option above but also update any phones that are mapped to use this template and currently registered to the PBX immediately with no need to reboot the phones.
