Creating Provisioning Scripts Using Provisioning Parameters 2 The following example condition triggers a resync if Line 1 failed to register for more than 5 minutes (300 seconds), and at least 10 minutes (600 seconds) have elapsed since the last resync attempt. $REGTMR1 gt 300 and $PRVTMR ge 600 Resyncing at a Specific Time The Resync_At parameter allows you to resync at a specific time. This parameter uses the 24-hour format (hhmm) to specify the time. To avoid simultaneously flooding the server with resync requests from multiple phones set to resync at the same time, the phone triggers the resync up to ten minutes after the specified time. For example, if you set the resync time to 1000 (10 a.m.), the phone triggers the resync anytime between 10:00 a.m. and 10:10 a.m. By default, this feature is disabled. If the Resync_At parameter is provisioned, the Resync_Periodic parameter is ignored. Configurable Schedules Profile resyncs and upgrades provide for automatic retries in case of failure, in addition to periodic configuration updates. Time intervals are specified by using three parameters, which are usually specified as a specific interval duration, in seconds. Starting with firmware version 3, these parameters allow the applicationlevel (macro time scale) retry schedule to be configured. These provisioning parameters are: • Resync_Periodic • Resync_Error_Retry_Delay • Upgrade_Error_Retry_Delay These parameters accept a single delay value (seconds). The new extended syntax allows for a comma-separated list of consecutive delay elements. Each delay element consists of a deterministic delay value, optionally followed by a plus sign and an additional numeric value that bounds a random extra delay. The last element in the sequence is implicitly repeated forever. For example, Resync_Periodic = 7200 Resync_Error_Retry_Delay = 1800,3600,7200,14400 Cisco Small Business IP Telephony Devices Provisioning Guide 50
