TSP Message to App data Party A: LINE_CALLSTATE (LINECALLSTATE_DISCONNECTED, LINEDISCONNECTMODE_REJECT) CallerID = A / CalledID = “” mod Calling = A / mod Called = “” A receives CallStateChangeEvent (Disconnect) BasicCallInitiatedFromTAPIUsingExternalCallControlonTranslationPatternandCEPMReturns Divert with Modified Calling and Called Parties Configuration Phone A, B are in cluster devices. B matches the translation pattern BXXX which has calling and called party transformation defined to transform A to A1 and B to B1 and External Call Control is also enabled. Procedure Application sends a lineMakeCall at A to call B. Result Dialed number B matches the translation pattern BXXX which has External Call Control enabled. This takes precedence and CUCM requests CEPM to get routing rule for B. CEPM returns divertTo = C, with ModifiedCalling = MA and ModifiedCalled = MB Call will be extended to C (modified calling and modified called in divert to routing directive, overrides the calling and called number transformation configured for translation pattern and the call is diverted to C) TSP Message to App data Party A: LINE_APPNEWCALL, LINE_CALLSTATE (LINECALLSTATE_DIALTONE/ LINECALLSTATE_DIALING) CallerID = A / CalledID = “” mod Calling = A / mod Called = “” A initiates call to B A receives NewCallEvent and CallStateChangeEvent (Dialtone/Dialing) A: LINE_CALLSTATE (LINECALLSTATE_PROCEEDING)/ LINE_CALLINFO CallerID = A / CalledID = B1 mod Calling = A1 / mod Called = B1 A receives CallStateChangeEvent (Proceeding) Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 745 Message Sequence Charts Basic Call Initiated From TAPI Using External Call Control on Translation Pattern and CEPM Returns Divert with Modified Calling and Called Parties
