OVERVIEW Busy Camp-on/Call Completion is a feature where the PBX will camp on a called party and inform the caller as soon as the called party becomes available given the previous attempted call cannot be successfully established. When trying to reach an extension which is already busy, the caller could request the UCM6XXX to camp on the called party by dialing the call completion request code.
CALL COMPLETION FEATURE CODE The feature code for call completion request can be modified on web GUI Call Features Feature Codes page. The default setting is *11 for “Call Completion Request” and *12 for “Call Completion Cancel”. Figure 1: Call Completion Feature Code P a g e UCM6XXX Busy Camp-on Guide...
