For the Adaptive Card click to retrieve a Parked call to work correctly, the RingCentral app has to have been run once, on the computer signed in as the Operator.
On occasion, a condition can occur where the file association gets lost.
This can be repaired by making a repair.reg file in the form below. Note, you will need to change the name to match the login name of the operator. The filename is unimportant but must end in .reg
Create this repair.reg file, modifying the name and import it as the operator.
