For the first time a queue, related to the shortage of network resources, is included in a model of overall telecommunication system with finite number of users and facilities which makes the model closer to the real system. The service in the queue depends on feedbacks of call attempts and of the state and duration of services in the overall system. The server of the queuing system has more than one exits. The results presented are a base for future development of tools for management, design, dimensioning and redimensioning of the system.
