• A UCCX CTI port shows out of service when it was dissociated from the application user or deleted in Unified CM; Cisco's fix is to restart the CCX Engine and recreate the affected call control group. in context
• A UCCX trigger goes out of service when its CTI route point was deleted in Unified CM or its directory number no longer exists; the fix includes removing orphaned DNs via Route Plan Report, recreating the route point and running a UCCX data resync. in context
• For a UCCX trigger showing Call Control Group is Unknown, Cisco says to reselect the call control group and, if the problem persists, restart the CTI Manager service on Unified CM and the CCX Engine. in context
• Cisco TAC filters Unified CCX Engine logs for Application Manager messages with the CLI command file search activelog /uccx/log/MIVR/* "%MIVR-APP_MGR" recurs ignorecase. in context
• Cisco TAC lists a script that is missing from Script Management or invalid, while still assigned to an application, as a cause of Application Manager partial service in Unified CCX. in context
• Cisco TAC runs Data Check and then Data Resync from Unified CCX Administration under Subsystems > Cisco Unified CM Telephony > Data Synchronization. in context
• For CM Telephony and Application Manager partial-service issues, Cisco TAC sets the Unified CCX Engine facilities APP_MGR, ENG, ICD_CTI and SS_TEL to Debug and XDebugging1 under Serviceability > Trace > Configuration. in context
• Cisco TAC lists a directory number deleted from or dissociated from the CTI route point as a cause of an out-of-service Unified CCX trigger, resolved by re-adding the DN and running data resync. in context
• Cisco TAC lists a trigger with no call control group assigned as a cause of a trigger configuration error, resolved by selecting the call control group and restarting CTI Manager and the Unified CCX Engine. in context
• Cisco TAC lists a deleted CTI route point on Unified CM as a cause of an out-of-service Unified CCX trigger, resolved by recreating the route point or running data resync and restarting services. in context
