Created by: Dan Coffey on 16-11-2009 01:32:29 PM During the testing of a JTAPI application the CiscoRTPOutputStartedEv event intermittendly does not arrives. This CiscoRTPOutputStartedEv event delivery failure happens intermittendly, once in 10-15 outbound calls.
When the remote phone answers the incoming call, the CUCM does send the CiscoRTPInputStartedEv event but the CUCM does not send the CiscoRTPOutputStartedEv event. If the application fails to get the initial CiscoRTPOutputStartedEv event and I put the IP Communicator on hold, the application does receive the CiscoRTPOutputStoppedEv event and when I select the Resume button on the IP Communicator the application gets a CiscoRTPOutputStartedEv event and the RTP stream can be established. JTAPI application places a call to a IP Communicator CUCM: System version: 7.0.1.11000-2 Platform: XP SP3 Java: JRE 1.6.0_17 Any idea what's wrong? Thanks, Dan

Note, the media events may not come in any particular order with the signaling events. You can attach the JTAPI logs (set detailed level, all-types) here, and we can take a look.

I see a jtapi.ini file, do I need that? I also see the com.cisco.services.tracing.* do I setup the LogFileTraceWriter Can you point me at the right doc's. Thanks, Dan

This file creates a jtapi.ini for you; then just make sure the jtapi.ini is in the path for your jtapi app. LogFileTraceWriter is available for managing tracing within your application, but takes a bit more to implement - most just use the jtapi.ini settings.

Check the classpath by running - set CLASSPATH. You should see CLASSPATH=c:\windows\java\lib\jtapi.jar; You can setup classpath manually by running 'set CLASSPATH=c:\windows\java\lib\jtapi.jar;.
