However, in the private telephone system described in the above-mentioned publication, if the owner of the mobile phone terminal is attending a conference, the owner of the mobile phone terminal is eventually called out. Cannot handle call. If the mobile phone is equipped with a so-called answering machine function that records messages from callers, it is possible to handle such a case after the meeting,
You cannot respond quickly. At this time, depending on the contents of the caller's errand, if a call is made to the place where the owner normally works (eg, workplace), the owner's agent (eg, a work colleague, secretary, etc.) responds to the errand. In some cases, it is possible to do so, but in that case, in the above-mentioned conventional system, it was necessary to make a new call, which was troublesome.

[0005]
