Due to the increase in popularity of mobile devices and mobile networks, the usage rate of VoIP has also increased. The flow consumption of types of VoIP has become very important from the limited mobile network data program. In recent years, the voice streaming server of Adobe Flash, Red5, has been increasingly used to realize the function of VoIP. Red5 is an open source media server and has good voice compression and video compression. However, it can only be executed on a PC computer. This is because Adobe Flash player has a hardware competence, such as microphone and camera lens. The flash phone is not supported or widely used on mobile devices. In this research, we propose a mobile device which can support Adobe AIR to obtain the competence of the hardware device and to use the Red5 library to communicate with the Red5 server. Experimental results showed that the proposed method allows mobile phones to call flash phones. Also, the flash phone bandwidth is about 4KBytes in comparison to the SIP phone, which makes it more suitable for use on mobile devices.
