callback_counters

This table provides metrics about calls that selected the virtual queue option and about the related callback attempts.

Unless noted otherwise with respect to a particular metric, any callback mentioned in this table shall be interpreted as a callback attempt made with respect to the service specified in the service_name field. Note that callback attempts are counted for the aggregation intervals in which the inbound calls that produced the associated callback requests entered the system.
