A method for processing calls for communciation equipment with a subscriber number ported from a first communication network of a first operator to a second communication network of a second operator, wherein in each communication network a database of ported numbers is formed, which is accessible from at least one gateway exchange, and in which the subscriber numbers ported from one operator to another operator are stored together with information about the network to which the subscriber numbers belong, and upon an incoming call at the network for a particular subscriber number, the called subscriber number is compared with the subscriber numbers in the database and on the basis of the result of that comparison routing information for the further processing of the call is composed.
