What is the function of the Cisco Unity Connection Call Handler?

Call Handlers in Cisco Unity Connection are used to process incoming calls, offering menus, playing announcements, and directing callers to various destinations like user mailboxes, extensions, or other call handlers based on their input (e.g., dialing an extension or pressing a key for a specific option).

While a call handler might direct a call to a queue, its primary function is not queuing calls itself; that is typically handled by ACD systems or specific call queue features.

Searching a list of extensions until a call is answered describes a hunt group or line group functionality, not the core function of a Unity Connection Call Handler.

While Call Handlers provide IVR-like capabilities, stating they allow 'customized scripts' implies a level of programming flexibility beyond the standard configuration options available in a basic Unity Connection Call Handler.
