The book is.. session initiation protocol (SIP) controlling convergent networks.. by travis russel... http://books.google.co.in/books/about/Session_Initiation_Protocol_SIP.html?id=WxXc0coHxyYC&redir_esc=y
pp. 48, paragraph 1 it says and I quote: "One SIP invite could carry within itself SDP descriptors for more than one session. This is so when supporting a conference call, as an example." Is this regarding the relationship between dialog and session? I mean a conference can have multiple dialog within a single session!
