9.1.2 Static DNS Record (Generic Domain Name)
This method is used for automatic provisioning when you are unable to manage your
DHCP server. If the provisioning server does not support using SIP SUBSCRIBE and
NOTIFY messages mechanism as described above and no response for the SIP
SUBSCRIBE message has been received, the phone tries to retrieve firmware and
configuration files using the following URL: tftp://ProvisioningServer/<Phone Model
Name>/
For example:
 The phone tries to obtain the following firmware file:
tftp://ProvisioningServer/310HD/310HD.img
 The phone tries to obtain the following configuration file:
tftp://ProvisioningServer/310HD/<MAC address>.cfg
(e.g. tftp://ProvisioningServer/310HD/001122334455.cfg)
It is the Administrator’s responsibility to configure a DNS entry called ProvisioningServer
on the DNS server and set it to the TFTP server IP address.
Note: If Generic Domain Name is used, the automatic provisioning mechanism
periodically tries to retrieve new firmware/configuration from Provisioning
Server domain name.
 To configure Static DNS Record:
 Using the Web:
1. Access the ‘Automatic Update page (Management tab > Automatic Update
menu > Automatic Provisioning).
