Are there any known problems with IVR/ICD when it is a co-resident with Cisco CallManager Attendant Console?
A. Cisco CallManager Attendant Console and Interactive Voice Response (IVR)/Interactive Call Distribution (ICD) both use Remote Method Invocation (RMI) for communication. The default RMI communication port is 1099. If Cisco CallManager Attendant Console starts up before IVR/ICD, it binds to port 1099 first. However, if Cisco CallManager Attendant Console starts up after ICD/IVR is up and the port 1099 is already taken, it looks for the first available port after 1099. Cisco CallManager Attendant Console works fine in either situation. However, IVR/ICD runs into problems if the 1099 port is already taken when it starts up. This error appears in the IVR/ICD logs: java.rmi.server.ExportException: Port already in use: 1099. There are two possible options to correct this problem: • Ensure that Cisco Telephony Call Dispatcher service starts after IVR/ICD. • Change the default RMI port in the IVR/ICD configuration.
