摘要
SIP of mVoIP services transmit media data such as video and voice, allowing for the provision of additional services, and the amount of usage on a wireless Internet such as WiFi is gradually increasing. While an increase in the user base is expected for mVoIP, a packet network is an open network which means anyone can easily gain access and so there can be various problems.
