Please let me know what architecture do VoIP applications use, P2P or Client-Server?

Thank you.

Solution

  • Some of each in general. There are three protocols involved, usually. One of them, for example SIP, is used to establish the connection. you need a server for that because someone has to establish the original connection; that means advertising availability and such. The other two are essentially always RTP and RTCP -- "real time protocol" and "real time control protocol", and those are better P2P, because you want fast transmission with no intermediate bottleneck.

    There's a nice article on the whole discussion here.
