XACLI – Special Commands – xfeedback (II)
EXAMPLE. User wants to know when calls are connected
and when calls are disconnected, without monitoring any
call data changes when the call is active:
This can be done by registering feedback on the events:
•
CallSuccessful
•
CallDisconnected
xfeedback register event/callsuccessful
OK
xfeedback register event/calldisconnected
OK
xcommand dial number:558458
*r Result (status=OK):
CallRef: 1
LogTag: 8
*r/end
OK
CONNECT
*e CallSuccessful:
CallRef: 1
LogTag: 8
Protocol: H323
Direction: Outgoing
CallRate: 768
RemoteNumber: "558458"

Outgoing: Off

xcommand disconnectcall call:1

NOTE! If sub-elements are removed from a status structure between transitions, the removed elements will be notified with an attribute
ghost=True
when feedback is issued. This allows for an external control system to be completely synchronised with the codec.
EXAMPLE. This example shows status for a call that is beeing
disconnected. The user has registered a feedback expression to
monitor all call changes (xfeedback register status/call).
When the call is active the Call element contains a large sub-struc-
ture. When the call is disconnected this status tree collapses, i.e.
the only information availible for a disconnected call is a Cause
element. All sub-elements that are being removed in this transition
ghost=True
are marked with a attribute when feedback is issued,
see below.
