Models of filing of messages at a switching center of messages are considered for the case of group recording of messages. The mathematical model is a queuing system with one server, two buffers, and a switch between the buffers. An iteration algorithm is proposed for calculating the probability characteristics. By virtue of a special transition probability matrix, it is possible to use this method for buffers with a capacity of the order of thousands.
