In-Depth Information
Note that UCCX communicates with CUCM using Java Telephony Application Programming Interface (JTAPI), and CUCM uses
a JTAPI user ID and password to authenticate the request from UCCX to begin the communication session. The JTAPI user ID and
password are automatically configured in CUCM during UCCX installation. Two JTAPI user IDs and passwords are required in a
redundant configuration.
In a redundant/fault-tolerant configuration, UCCX is able to communicate with up to two CTIManagers (a CUCM subsystem that
enables JTAPI communication) in a CUCM cluster. However, UCCX actively communicates with only one CTIManager at one time.
If the active CTIManager fails, UCCX fails over to the redundant connection with the second CTIManager. At the time of failover,
calls in progress survive, though phones that are registered with a failed CUCM must reregister with another CUCM when existing
calls are complete.
Once the just described basic configuration of UCCX is complete, CAD and CSD can be installed.
Troubleshooting
When troubleshooting UCCX, it can be useful to examine trace files. By default, UCCX sends information about subfacilities to trace
files.
It is possible to modify trace defaults by going to
System, Tracing
in UCCX (CRS) Administration. Tracing produces log files that
record UCCX component activity.
You can specify a trace level of debugging and/or alarm tracing (or no selection), along with a facility and subfacility. Facilities
include MIVR (workflow application framework), MCVD (cluster framework), MADM (CRS Administration page), MEDT (editor),
and MARC (Archive framework).
Subfacilities include, for example, SS_CMT (CMT subsystem), SS_DB (database subsystem), SS_HTTP (HTTP subsystem),
SS_MRCP_ASR (MRCP ASR subsystem), SS_MRCP_TTS (MRCP TTS subsystem), SS_TEL (JTAPI subsystem), STEP_CALL_
CONTROL (call control steps), STEP_SESSION (session steps), STEP_USER (user steps), STEPS_DB (database steps), STEPS_
GENERAL (general steps), and so on.
JTAPI is a common cause of issues with UCCX. You can quickly verify the status of the JTAPI subsystem by going to
System,
Control Center
.
