ATTENTION
If an outgoing or incoming call is made or received on the IP Phone 1535 during the software update process, the update process is halted for the duration of the call.
FTP software update process
The IP Phone 1535 can perform updates to its installed system software, by connecting to a locally provisioned FTP update server and automatically detecting, downloading, and installing any available updates it finds there.
The sequence for a successful
1535 is as follows:
1.The IP Phone 1535 opens a connection to your configured FTP server.
2.Upon successful connection, the Username and Password (ipphone / 15354all) are sent automatically by the IP Phone 1535 for authentication on the FTP server.
3.The IP Phone 1535 retrieves the FirmwareUpdateRequest.acfg file for its currently installed version from the [software version] directory of your FTP server.
4.The FirmwareUpdateRequest.acfg file points the IP Phone 1535 to information about available upgrades. In order to successfully complete the upgrade process, you must update this file within the existing software directory for any new FTP image that is placed on the FTP server.
5.If the firmware on the phone is found to be current, the FTP connection is closed.
6.If the firmware is not current, the IP Phone 1535 retrieves and applies the upgrade, according to the directory specified by the FirmwareUpdateRequest.acfg file.
7.After the successful download and install of the available upgrade, the IP Phone 1535 determines itself to be current and closes the active connection to your FTP server.
