Ganesh: >From the RFC,
"A back-to-back user agent (B2BUA) is a logical entity that receives a request and processes it as a user agent server (UAS). In order to determine how the request should be answered, it acts as a user agent client (UAC) and generates requests. Unlike a proxy server, it maintains dialog state and must participate in all requests sent on the dialogs it has established. Since it is a concatenation of a UAC and UAS, no explicit definitions are needed for its behavior." Clearly it cannot a UAC-UAC concatenation; it is a server on one side and a client on the other side. As long as it processes requests it has a UAS functionality.

It refers to a UAS concatenated with a UAC for incoming requests into the UAS. Would it be incorrect to use the term b2bua to refer to a UAC-UAC concatenation?
