Abstract: A system and a method for collecting and presenting subscriber number information for a calling subscriber sent by CTI system signalling over a stationary telecom network. The system utilizing the method includes for each individual telephone line a line processor (10-15) with a memory (4-9) for buffering. The memory is over a bus (3) interconnected to a central processor or a main processor (1) for collection of the incoming number information of each line. Additionally the system includes a unit for conversion of incoming CTI system signalling at each line processor into binary code constituting number information, each line processor (10-15) further including a number of subfunctions for handling and forwarding of number information received, and each line processor having a unique identification being forwarded together with number information for presentation.
