Abstract
A communication exchanger has a memory which memorizes a presence state table for all of users and a forwarding destination table for each of the users. In the presence state table, presence information of all users is registered. In the forwarding destination table, forwarding destination information classified by each presence of the user is registered. Upon receiving a call, the exchanger retrieves the presence information of the corresponding user from the presence state table. The exchange further retrieves the forwarding destination information according to the presence information from the forwarding destination table to forward the call. When the presence information is rewritten, the forwarding destination of the call is changed without rewriting the forwarding destination information.
