The most essential purpose of the database connection in a call center server is the customer identification. This basically means that the call center can get all the known information about a customer in the exact moment the customer calls the system or a call center agent dials a customer's number.

Customer identification can be the base of the call routing, for example. Let's assume that your company has three different provided services, and you have three groups of support agents, each group is a set of professionals on the service assigned to their group. When a customer calls the call center server checks the customer information from the database and identifies them as somebody who purchased for the second service. In this case it is essential that the call will be directed to an agent who is assigned to the second service.
