Abstract

A communication system is disclosed including at least a communication network, one caller party equipped with a communication device by using of which the caller party may originate a communication, one called party equipped with communication means by using of which the called party may response to the communication originated by the caller party and one or more network elements arranged in communication network for arranging the communication between the caller and called parties and which of network elements at least part are arranged to be operated as VoIP system elements in order to arrange VoIP-based communication. In communication system is arranged to be implemented as features a protocol enabling an availability of a presence information of at least the communication means of the called party and an universal designation feature in order to form a destination address for the communication from the caller party to the called party. In the said system in connection with the origination of the communication using of the presence information is arranged to be determined a preferred location of the called party and a data connected to that and based on the determined preferred location of the called party is arranged to be generated the destination address of the called party by using of the universal designation feature and the data connected to the preferred location.
