<p>The present invention enables a capability to identify high spending, or high tier, customers of packet-switched network services, e.g., VoIP network services and provide them with a higher level of service than lower paying, or normal tier, customers. For example, these highly valued customers can be offered free trials or special promotions of new service features and their calls into customer care can always be routed to live, highly experienced customer care agents.</p> |
