JTapiCallInitiated indicates that a line on a monitored device has gone off-hook.

A phone going off-hook does not correlate to a phone call. If building an application that is concerned foremost with knowing a phone has made a call, then consider using the JTapiCallEstablished event instead for the basis of your script trigger.

Subsequent events indicate important state changes of the call. JTapiCallActive indicates that the call has been answered by the remote party. JTapiHangup indicates that call has been gone on-hook if JTapiCallActive has not yet occurred.

The term 'CallInitiated' is a very strict interpretation of a JTAPI call; when a phone is taken off-hook, a new call is created within Cisco Unified Communications Manager, although there is not yet a remote number dialed by the phone device. Therefore, there is no To parameter associated with this event.
