In this article, we propose a disaster communication system using ad-hoc mesh network. In this system, we use the Etherphone which is communication technology using only the data link layer and the physical layer of OSI reference model. In previous research it was shown that the wireless Etharphone can perform ad-hoc communication. However, it is not shown that voice communication can be performed with the wireless Etherphone. It shows that voice communication is possible with the wireless Etherphone.
