Peer-to-Peer Internet Telephony using SIP
... We propose a P2P Internet telephony architecture using SIP. There are two main motivations for P2P-SIP: a fully distributed model to increase robustness, and the ability to deploy without modifying controlled infrastructure such as DNS. We analyze various design alternatives and present our P2P-SIP ...
