• Peer firmware sharing does not function unless multiple phones are set to upgrade at the same time.
When a NOTIFY is sent with Event:resync, it initiates a resync on the phone. Example of an xml that
can contain the configurations to initiate the upgrade:
http://10.77.10.141/profile.xml
• When you set the Peer Firmware Sharing Log server to an IP address and port, the PFS specific logs are
sent to that server as UDP messages. This setting must be done on each phone. You can then use the log
messages when troubleshooting issues related to PFS.
Note
Peer_Firmware_Sharing_Log_Server specifies UDP Remote syslog server hostname and the port. The port
defaults to the default syslog 514.
For example:
<Peer_Firmware_Sharing_Log_Server>192.168.5.5</ Peer_Firmware_Sharing_Log_Server>
To use this feature, enable PFS on the phones.
Enable Peer Firmware Sharing
You can enable Peer Firmware Sharing (PFS) when you want a phone to find other phones of the same model
or series on the subnet and share updated firmware files. The phones are organized into a hierarchy and one
of the phones in that hierarchy acts as a root phone. After the hierarchy formation, the root phone downloads
the firmware image from the load server and then transfers the firmware to other phones in the hierarchy.

Profile Authentication
Profile Authentication allows phone users to resynchronize the provisioning profile onto the phone.
Authentication information is required while the phone tries to resynchronize and download configuration
file for the first time and gets an HTTP or HTTPS 401 authentication error. When you enable this feature, the
Profile account setup
screen is displayed on the phone for the following situations:
• When the HTTP or HTTPs 401 authentication error occurs during first-time provisioning after the phone
