InvalidStateException : Did not meet pre conditions. Call 2 merges Conn for D created on GC1 Call 2 cleaned up Chaperone C1 starts recording Chaperone C1 tries to redirect the call Call Is Redirected to a Hunt List of Chaperones and the Chaperone Conferences in the Called Party From Application Configuration A calls X, X’s DN matches the translation pattern where External Call Control is enabled. CUCM redirect the call to the hunt pilot B. Call is intercepted by the chaperone and the chaperone C1 answers the call. After talking to A briefly and discovered that A intended to talk to D, the chaperone C1 starts to establish a conference to D. C1 initiates a consult call to D. A new global call id GC2 is created. CUCM rings D’s phone and D answers the call. C1 invokes GC2.conference(GC1) from application. At this step, request for establishing the conference would fail. Jtapi would throw InvalidStateException with the error code as “Call state not valid”. In order to establish a conference successfully, application must invoke the conference by passing the CI of the call in which chaperone is the controller as the primary CI. So in this case, if application invokes GC1.conference(GC2), it would be able to establish the conference successfully and if application invokes GC2.conference(GC1), Jtapi would throw an exception.
