Manually Initiating Firmware Update; Check-Sync Upgrade - Plantronics IP40 Administration Manual

5.2 Manually initiating firmware update

The administrator can manually update the IP40 headset adapter to the latest firmware
by pointing the IP40 at the correct firmware directory on the enterprise file server or
Plantronics public web site and changing the polling setting to Relative with the desired
time interval. Before upgrade the IP40 will check that it is not in an active call. If it is it
will defer upgrade to after the call is terminated.
After a Relative firmware upgrade, remember to disable polling for firmware and
configuration updates.

5.3 Check-sync Upgrade

The IP40 headset adapter can respond to an unsolicited notification from a
management system. When this feature is enabled and the IP40 headset adapter
receives this "check-sync" SIP NOTIFY request, it compares the firmware version it is
currently running with the version stored on the server. If the versions are different, the
adapter immediately starts a firmware update.
The NOTIFY request is an unsolicited NOTIFY for the "check-sync" event. It has a
unique Call-ID. The Request URI has the MAC address of the adapter in capital
hexadecimal digits in the user part, and the IP address of the adapter (and port number
if a non-default source port number is used) in the host part. The From header is a URI
on the registration domain. For example, a partial check-sync message corresponding
to our example in Section 4 is below (Via, CSeq, and Call-ID headers are not shown).
NOTIFY sip:00087B06D175@10.1.7.155 SIP/2.0
From: <sip:10.1.3.32>;tag=0sdhug3bsy9nh
To: <sip:00087B06D175@10.1.7.155>
Event: check-sync
Contact: <sip:4081@10.1.7.155>
This feature is enabled only if the SUBSCR_0_SIP_UA_DATA_SERVER_ID and
ENABLE_SIP_MESSAGE_ENCRYPTION are explicitly set to 0. Note that no
authentication is provided for the check-sync request.
If VOIP_LOG_AUTO_UPLOAD is set to 2, the IP40 headset adapter will also use HTTP
to upload its Debug Log before attempting a Firmware Update.
