CTI connects a PBX with a computer, so that the computer manages the telephone calls. Using CTI has the following advantages: - Personal and rapid approach of the customer. The customer is immediately recognised by the telephone number. With a report of unanswered calls it is also possible to call customers back the same day. This service enhances a customer-friendly image. - Efficiency through time savings. All customer information is instantly available, so the interview time is reduced. Outgoing calls are made with a mouse click from Invantive, which makes entering telephone numbers unnecessary. - Comfort and stress reduction.

The notes can be stored and consulted at the next contact. - Cost savings. The use of staff can be adjusted at peak times. The telephone traffic is fully registered. Dialling from your PC and using the automatic popups saves a considerable amount of time, and that means cost savings. - Better accessibility.
