SIP is a peer-to-peer protocol. The peers in a session
are called User Agents (UAs). A user agent can
function in one of the following roles:
1. User agent client (UAC) - A client application that
initiates the SIP request.
2. User agent server (UAS) - A server application that
contacts the user when a SIP request is received
and that returns a response on behalf of the user.
Typically, an SIP end point is capable of functioning as
both a UAC and a UAS, but functions only as one or
the other per transaction
