2.4.5 Timing of Configuration File Downloads
Each device can download configuration files at the following times.
–When the device starts up
–At regular intervals
–At a specific time of day
–When directed to download by the SIP server
Regular intervals
Specified by using CFG_CYCLIC_INTVL="{number of minutes}".
For example, CFG_CYCLIC_INTVL="4320" configures the device to download configuration files every three
days (4320 minutes) beginning when the device starts up.
Specific time of day
Specified by using CFG_RESYNC_TIME="{time}". For example, CFG_RESYNC_TIME="23:00" configures the
device to download configuration files each day at 11:00 PM.
When directed by the SIP server
If a setting needs to be applied immediately, the SIP server can send a NOTIFY message to the devices
directing them to download their configuration files. This feature is enabled by specifying
CFG_RESYNC_FROM_SIP in the configuration file.
Example of the NOTIFY message sent from the SIP server:
NOTIFY sip:1234567890@sip.example.com SIP/2.0
Via: SIP/2.0/UDP xxx.xxx.xxx.xxx:5060;branch=abcdef-ghijkl
From: sip:prov@sip.example.com
To: sip:1234567890@sip.example.com
