Special Scenarios
-----------------
When the caller is called back in the context of call completion, XiVO attempts to call the callee
in a way similar to directly calling the user.
There are four special scenarios:
This means that if, for example, the callee has enabled the `Do Not Disturb` functionality, then the
call completion callback will ultimately fail to reach the callee. The behaviour is similar if the
user has an unconditional call forwarding, a schedule, a call permission or a preprocess subroutine,
etc.
* the call completion will not activate
* the call completion will activate and call back for the original called party
* the call completion will activate and call back for the rerouted called party
* the call completion will activate and call back for the original called party but fail to join him
In the following scenario:
Call completion will not activate
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#. Alice attemps to call Bob.
#. Bob is currently on a phone call, so he doesn't answer the call from Alice.
#. Bob has enabled a forward on no answer to Carol, so Alice is redirected to Carol.
#. Carol begins to ring.
#. Alice hangs up.
#. Alice then dial \*40 to request call completion.
Scenario: Alice tries to call Bob, but the call is redirected to Charlie. When activating call
completion, Alice hears that the call completion can not be activated.
This occurs when Bob redirects/rejects the call with any of the following:
* Unconditional call forwarding towards Charlie
* Closed schedule towards Charlie
* Call permission forbidding Alice to call Bob
* Preprocess subroutine forwarding the call towards Charlie
Call completion will activate and call back for the original called party
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Scenario: Alice tries to call Bob, but the call is redirected to Charlie. When activating call
completion, Alice hears that the call completion is activated and eventually Alice is called back to
speak with Bob.
This occurs when Bob redirects/rejects the call with any of the following:
* No-answer call forwarding towards Charlie
* Busy call forwarding towards Charlie
Call completion will activate and call back for the rerouted called party
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Scenario: Alice tries to call Bob, but the call is redirected to Charlie. When activating call
completion, Alice hears that the call completion is activated and eventually Alice is called back to
speak with Charlie.
This occurs when Bob redirects the call with any of the following:
* Boss-Secretary filter to the secretary Charlie
Call completion will activate and call back for the original called party but fail to join him
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Scenario: Alice tries to call Bob, but the call is redirected to Charlie. When activating call
completion, Alice hears that the call completion is activated and eventually Alice is called back to
speak with Bob. But when Alice answers, Bob is not called. If Alice activates call completion again,
she will hear that the call completion was cancelled.
This occurs when Bob redirects/rejects the call with any of the following:
The call completion request will monitor the first phone that was called, i.e. it will monitor Bob's
phone. When Bob becomes not busy, the call completion callback will try to call Bob's on behalf of
Alice.
* Do Not Disturb mode
* a new call forwarding rule that was applied after Alice activated call completion:
* Unconditional call forwarding towards Charlie
* Closed schedule towards Charlie
* Call permission forbidding Alice to call Bob
* Preprocess subroutine forwarding the call towards Charlie
