The ReasonCode: 2362179618 in this error message translates to CTIERR_INVALID_DEVICE_NAME = 0x8CCC0022.
In order to overcome this error:
Check the name of the CTI Route Point/CTI port in the application configuration.
Make sure that the CTI Route Point/CTI port name in the application configuration matches the CTI Route Point/CTI port name in the Cisco Unified Communications Manager (CallManager).
If step 1 and 2 do not solve the problem, restart CTIManager.
