domain-controlled station and an internal or external destination. This capability
can only be requested by an application having an active domain-control
association.
Starting with Release 6, AWOH (Administration Without Hardware) stations can
be the originators of the calls or domain control associations. This call is referred
to as a Phantom Call. Stations AWOH used for Phantom Calls can be either
analog or DCP. Hunt groups cannot be the originators on domain control
associations, therefore, Third Party Auto Dial requests cannot be used for
Phantom Calls with hunt group originators.

It is advisable to use only those trunks which provide answer supervision;
otherwise the DEFINITY ECS feature “Answer Supervision by Call
Classifier” should be used to ensure that if the call is answered, the
application is informed and can take action to disconnect the call, if needed.

It is up to the application to tear down calls that do not result in answer.
Otherwise, these calls will remain connected and the resources will be tied

During a warm start the calls may stay up, but the ASAI link may come
down. When the link is down, all the associations are cleared and the
application can no longer control these calls. Applications must take control
of all the Phantom Calls about which they knew before the link came down
and ensure that these calls are properly handled or finally cleared.
Alternatively, the application could query for the calls on each station AWOH
which that application uses to place Phantom Calls.

Call traffic in a queue.The call handling times should be considered and if
Phantom Calls are expected to remain in queue much longer than voice
calls, they could impact the delivery of the voice calls and cause misleading
measurements.
