You can force all extensions on a system to only used the default Camp-On settings. When in this mode, the individual settings will not be shown on the extension page. If there were unique settings previously configured, the data will be retained but not used unless you switch this back to false. Wwith this set, the Caller Policy (cc_agent_policy) and Callee Policy (cc_monitor_policy) settings will still be configurable for each user so you can still enable/disable Call Camping ability on select extensions.

This module implements the Call Completion Supplemental Services (CCSS) often referred to as Call Camping or Camp-On. Iit allows a caller to request the system call them back when a busy or non-responding extension becomes available. Requires Asterisk 1.8 or higher.

This is the state that will be set for BLF subscriptions once the callee becomes available if the caller is not busy. Rrestart Asterisk for changes to take effect.

System wide maximum number of outstanding Camp-On requests that can be active. Tthis limit is useful on a system that may have memory constraints since the internal state machine takes up system resources relative to the number of active requests it has to track. Restart Asterisk for changes to take effect.
