Managing phone configurations
The FortiVoice unit provides the default configuration templates for the phone types with Limited support level. In most cases, there is no need to modify the templates. If you do need to make changes to a template (for example, change the IP address of the NTP server), make sure the format matches that of the default template. Otherwise, phone auto-provisioning will not be possible. This is because the template is part of the configuration file generated for the phone type and will be sent to a phone of this type through auto provisioning. For details, see “Configuring SIP phone auto-provisioning”.
The phones with Comprehensive support level do not display their configuration templates because the FortiVoice unit fully supports the phones.
You can also manage the phone firmwares on the FortiVoice unit.
Once you have modified the templates or uploaded a new firmware, they are saved on the FortiVoice unit. To send them to the phones, choose a low traffic time and reboot the phones. For information on rebooting the phones, see “Setting up local extensions”.
