Com.cisco.cti.protocol.FailureResponse

Question

Hi all,
I have a callmanager 6.1.1(pub and subscriber) connected to a ipcc express with 2 nodes, last week we had to remove the subscriber from the callmanager cluster. After that we notice that same calls from the ipcc to the agents were beeing drop with the folowing error message on the ipcc express:

Is there any documents on the cco that explains this error message or thus any one knows what could be this error
Thanks

Answer 1

Decoding the error cause it is:
const unsigned long int CTIERR_ILLEGAL_HANDLE
=                                0x8CCC0004;
I suspect there may be something wrong in the call before this message and this is an after effect. We would need the JTAPI client logs to confirm, but this should be investigated from the CUCM side as it looks as though the error is in the JTAPI layer.
