PROBLEM TO BE SOLVED: To solve the problem in which: when a destination is selected by use of a destination list, convenience is reduced if a destination candidate selected frequently is not included in the destination list, or if a destination candidate selected infrequently is included in the destination list; because the selection frequency of a destination candidate differs per communication start request source side, in the case where multiple start request source sides use a prescribed destination list, if the prescribed destination list is changed tailored to a certain start request source side, convenience may be reduced when a destination is selected at another start request source side.SOLUTION: According to the invention, in the case where first destination list information is changed to second destination list information, the second destination list information and start request source information indicating a start request source side which is a change request source of the second destination list information are managed in association with each other. This brings in an effect to make it possible to change and use the first destination list information per start request source side without having influence on other start request source sides using the first destination list information. |
