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.
! WARNING:
Do not place Phantom Calls over trunks which do not provide disconnect supervision. These calls will be denied.
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 forever.
Since Phantom Calls can be directed anywhere, it is up to the customer to configure the application and the DEFINITY ECS in such a way that the vector commands executed for such calls make sense.
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.
The customers should be careful when mixing voice call traffic with Phantom 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.
