For more information on this see http://support.microsoft.com/default.aspx?scid = kb;en-us;248611 JTAPI Behavior Scenario JTAPI returns the DSCP value received from CTI in StartTransmissionEvent to the application. Application uses the JTAPI getPrecedenceValue() API to query for the new DSCP value, in CiscoRTPOutputStartedEvent. JTAPI returns the DSCP value received from CTI in ProviderOpenCompletedEvent to the application. Application uses the JTAPI getAppDSCPValue() API to query for the new DSCP value, when it gets ProviderInServiceEvent. QSIG Path Replacement The following table shows the JTAPI events that are delivered to applications when calls between PBXs that are connected by Q.Signaling (QSIG) trunks are transferred and forwarded. This table also shows the events that are delivered to applications when the real-time path (RTP) is optimized by the QSIG Path Replacement feature. Calls going out on a QSIG trunk may not have a connection for the far end if any translation pattern is changing the pattern. In other words, when the application sees two calls in the trombone case, B may not serve as the common connection on the calls. Event Action No. These events get delivered to applications: CallCtrlConnectionEstablishedEv A CallCtrlConnectionDisConnectEv B OpenLogicalChannelEvent if C is a CTI device (Dynamically registered CTIPorts and RP) A registered with CM1, B is registered with CM2, and C registered with CM3. A calls B (GC1); B transfers the call to C. The application is monitors C. The PR feature replaces the path after the call gets connected to C. The same action applies to scenarios that involve call forward at B. (The called party transfers the call.) 1 Cisco Unified JTAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 1392 Message Sequence Charts QSIG Path Replacement
