+==========
+Schedulers
+==========
+
+Schedulers provide an automatic mechanism to enable, disable, and toggle the **Reject Calls** flag in **Customer Auth**, **Destination**, **Dialpeer**, and **Gateway** objects.
+
+
+Scheduler Fields
+================
+
+Id
+    Unique scheduler identifier.
+
+Name
+    User-friendly scheduler name.
+
+Enabled
+    Only enabled schedulers are processed by the system.
+
+Use Reject Calls
+    When enabled, the scheduler applies the **reject_calls** flag to **Customer Auth** and **Destination** objects to block traffic.
+
+Current State
+    The current operational state of the scheduler. The system automatically recalculates this state every 2 minutes.
+
+Timezone
+    The timezone that determines when the scheduler operates.
+
+
+Ranges Configuration
+====================
+
+By default, a scheduler allows all traffic. To define when traffic should be blocked, create one or more **ranges**. Range Attributes:
+
+Months
+    Months during which blocking will be applied. An empty value means *any month*.
+
+Days
+    Days of the month when blocking will be applied. An empty value means *any day of the month*.
+
+Weekdays
+    Days of the week when blocking will be applied. An empty value means *any day of the week*.
+
+From Time
+    Start time of the blocking period. An empty value means *start of the day*.
+
+Till Time
+    End time of the blocking period. An empty value means *end of the day*.
