SIP REFER The following section describes the scenarios that might be encountered during a SIP REFER. There are two categories of REFER scenarios: IN-Dialog and OutOfDialog. IN-Dialog REFER Scenario There are 11 scenarios (A through K) described in the sections that follow for IN-Dialog REFERs. Scenario One A (SIP UA in cluster/in control) is in a call with B. A (referrer) REFERs B (Referee) to C (Refer to target), C is Ringing.
