Problems of VOIP and Spam over Internet Telephony

Main Article Content

วรพล ลีลาเกียรติสกุล


- VoIP has been widely used for years, because of its lower service cost than the traditional telephone call. However, people or users need to be aware of security on VoIP system because the voice data has to traverse on public networks and vulnerabilities on VoIP system itself. Therefore, this article presents how VoIP system works including supported protocols. Additionally, security analysis is also provided to show vulnerabilities and threats on VoIP system. Finally, SPIT (SPam over Internet Telephony) and Anti-SPIT frameworks are explained since SPIT is currently one of the most recognized problems on VoIP system.
