    Download the UCXSI Developer Guide and Sample Codes from http://developer.cisco.com/web/ucxapi/docs

7. Sample UCXSI Configuration.
    ! Defining XML Transport Parameters
      ip http server                  --- Enables the Cisco web browser user interface on the local Cisco Unified CME router
      ixi transport http             --- Specifies the XML transport method and enters XML-transport configuration mode.
       response size 64         --- Sets the response buffer size. In kilobytes
       no shutdown                 --- Enables HTTP transport
       request outstanding 1 --- Sets the maximum number of outstanding requests allowed for the transport type
       request timeout 60       --- Sets the number of seconds to wait, while processing a request, before timing out.
    ! Defining XML Application Parameters
      ixi application cme
       no shutdown      --- Enables XML communication with the application
    ! Defining Authentication for XML Access
      telephony-service
       xml user cisco password cisco 15
    ! Configuring a Session Server in Cisco Unified CME
      voice register session-server 1
       keepalive 60
       register-id OCT_CME      --- This name should match Session Server in Provider configuration file
       cti-aware
    !
      voice service voip
       no cti shutdown      --- enable CSTA client to monitor and control directory number
       sip
       registrar server expires max 120 min 60
    !
      voice register global
       mode cme      --- enter to configure SCCP Phones
    ! Configuring a ephone-dn in Cisco Unified CME
      ephone-dn 1
       number 201
       cti watch      --- have to enable this to monitor phone
      ephone-dn 2
       number 202
       cti watch      --- have to enable this to monitor phone

8. Debug commands to enable on Router for UCXSI.
    debug ccsip messages
    debug cti all

9. What configuration settings are required in the CallManager express to restrict the access to the uaCSTA protocol?
    However if “cti shutdown” is configured, those CSTA requests (basically the INVITE for session establishment) will be denied so CTI activities will be blocked.

10. What benefit is there to REGISTER to the CallManager Express as a session server?
      Session server serves as a heart beat between application (SDK) and CUCME. If any side crashes, the other side has a way to clean up its dangling sessions.

11. SDK reported a CMEProviderOutOfServiceEvent.
      If the Session Server name in CMEProviderConfig does not match the register-id configured on CUCME, “no cti shut” is not configured on CUCME or the      user/password inCMEProviderConfig do not match those configured on CUCME,SDK will report an CMEProviderOutOfServiceEvent through      CMEProviderListener.onProviderOutOfService().

12. SDK reported a CMEResourceUnvailableException.
      If a wrong local host IP address, wrong CUCME IP address or wrong local port is configured in the CMEProviderConfig,SDK will throw a      CMEResourceUnvailableException

13. How to make a call from a Virtual Terminal.
     CMEProviderConfig cmeProviderConfig = new CMEProviderConfig("C:\\UCXSI\\ucxsi_sdk.conf");
     CMEProvider myProvider = ProviderManager.getProvider(cmeProviderConfig,"CME_Provider");
     CMEQueueTerminal virPhone = (CMEQueueTerminal) myProvider.createTerminal (mac, CMEAbstractTerminal.Type.QUEUE, "VIR");
     CMEQueueTerminal virPhone = (CMEQueueTerminal) myProvider.createTerminal (mac, CMEAbstractTerminal.Type.QUEUE, "VIR");
     CMEQueueAddress queAddress = (CMEQueueAddress) myProvider.createAddress (number, CMEAbstractAddress.Type.QUEUE_DN);
     virPhone.addAddress (queAddress, cstaListener);
     CMECall call = myProvider.createCall (CMECall.Type.DIRECT);
     call. connect (virPhone, queAddress, destDn, (CMEResponseInterface) cmeResponseListener, false);

14. Is it possible to monitor ephone-dn up-down status?
      Yes, whenever an ephone-dn status goes from up to down (Eg. phone shutdown, phone reset, user logout etc), an CMEOutOfServiceEvent is reported via      CMECSTAListener.onNotification ().Whenever an ephone-dn status goes from down to up (Eg. phone registers with CUCME, user login etc), a      CMEBackInServiceEvent is reported via CMECSTAListener.onNotification ().
