• 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:
“Event:resync;profile="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
You can also configure the parameters in the phone configuration file with XML(cfg.xml) code.
Before you begin
Access the phone administration web page. See Access the Phone Web Interface, on page 104.
Procedure
Step 1 Select Voice > Provisioning.
Step 2 In the Firmware Upgrade section, set the parameters:
a) Set the Peer Firmware Sharing parameter.
You can configure this parameter in the phone configuration XML file (cfg.xml) by entering a string in
this format:
<Peer_Firmware_Sharing ua="na">Yes</Peer_Firmware_Sharing>
Options: Yes and No
Default: Yes
b) Set the Peer Firmware Sharing Log Server paramter to indicate the IP address and the port to which
the UDP message is sent.
For example: 10.98.76.123:514 where, 10.98.76.123 is the IP address and 514 is the port number.
You can configure this parameter in the phone configuration XML file (cfg.xml) by entering a string in
this format:
<Peer_Firmware_Sharing_Log_Server>192.168.5.5</ Peer_Firmware_Sharing_Log_Server>
Peer_Firmware_Sharing_Log_Server specifies UDP Remote syslog server hostname and the port. The
port defaults to the default syslog 514.
Step 3 Click Submit All Changes.
Specify the Profile Authentication Type
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
