As in Call Manager, you can specify the level of traces that you want to enable but we will not cover this now. Let’s see the common issues.

Most of the times , issues are due of a mistake with the JTAPI. You can find easily the root cause with the Control Center as it will give you a status of the engine. Then with these status, you can see in which direction you have to go.

  • In-Service : Indicates a full operational mode (all CTI ports, CTI route points and associated applications are successfully initialized)
  • Initializing : Indicates that the subsystem is initializing the CTI route points, ports and associated applications
  • Partial Service : Indicates that the JTAPI subsystem was unable to initialize one or more CTI route points or ports. Most of the time, it is due to a misconfiguration, so check that route points/ports exist , are correctly configured and associated with the JTAPI on Call Manager
  • Out-Of-Service : Indicates that none of the CTI route points and ports were correctly initialized. It can occur for a number of reasons as follows:
    • JTAPI Provider on Call Manager down
    • No CTI ports or route points configured
    • Username/password incorrect
    • CRS is unable to resolve the Call Manager’s DNS name
    • No connectivity between the CRS and Call Manager
