<p>When calling a telephone, it is judged whether the calling destination telephone is an IP telephone (S17). When the judgment result is affirmative, a flag (2) is turned on (S19). Then, a marker indicating that the destination telephone is an IP telephone is added to the telephone management information of the destination registered in the telephone book in the memory (S59, S65). Thus, when calling the same destination next time and after, it is possible to know whether the destination telephone is an IP telephone according to the presence/absence of the marker in the telephone book before connection with the destination.</p> |
