DescriptionParameter
Controls requests for resync operations via a SIP
NOTIFY event sent from the service provider proxy
server to the IP Telephony device. If enabled, the
proxy can request a resync by sending a SIP NOTIFY
message containing the Event: resync header to the
device.
Default: Yes

upgrade occurs. If Yes is selected, sync is triggered.
Default: Yes

profile is not received from the server. This can be
overridden by this parameter. When it is set to No,
the device accepts a file-not-found response from
the server as a successful resync.
