For example, CFG_RESYNC_TIME="23:00" configures thedevice to download configuration files each day at 11:00 PM.When directed by the SIP serverIf a setting needs to be applied immediately, the SIP server can send a NOTIFY message to the devicesdirecting them to download their configuration files. This feature is enabled by specifyingCFG_RESYNC_FROM_SIP in the configuration file.Example of the NOTIFY message sent from the SIP server:NOTIFY sip:1234567890@sip.example.com SIP/2.0Via: SIP/2.0/UDP xxx.xxx.xxx.xxx:5060;branch=abcdef-ghijklFrom: sip:prov@sip.example.comTo: sip:1234567890@sip.example.comDate: Thu, 1 Jan 2014 01:01:01 GMTCall-ID: 123456-12345678912345678CSeq: 1 NOTIFYContact: sip:xxx.xxx.xxx.xxx:5060Event: check-syncContent-Length: 0For more information about the related parameters• CFG_CYCLIC (Page 235)• CFG_CYCLIC_INTVL (Page 235)• CFG_RESYNC_TIME (Page 235)• CFG_RESYNC_FROM_SIP (Page 236)46 Administrator Guide Document Version 2014-052.4.5 Timing of Configuration File Downloads
