Feasibility study of VoIP integration into the MYSEA environmentTse, Lily. 09 1900 (has links)
Voice over Internet Protocol (VoIP) is becoming popular due to its low cost and the management advantages it offers over traditional PSTN phone systems. VoIP is widely implemented with H.323 and Session Initiation Protocol (SIP) standards. However, both protocols are poorly designed for networks with common security solutions such as firewalls and Network Address Translation (NAT). This project is a feasibility study of SIP-based VoIP integration into the Monterey Security Architecture (MYSEA), a multilevel secure environment that uses NAT as a security mechanism. A gathering of comparative studies on VoIP protocols was performed to guide the selection of SIP as the test protocol. A set of experiments was devised and conducted using SIPbased softphones for this study. The insights gained from the experiment provide useful insights to the MYSEA project concerning VoIP security.
