3.PoC customer end A determines to invite PoC user B to participate in PoC session, and " invitation " request is sent to PoC server A.
4.PoC server A sends to the PoC server B in PoC user B local network by " invitation " request.
5.PoC server B mandate PoC user A, and select the answer-mode configuring, and 183 " session progress " response is sent to PoC server A.
6.PoC server A sends to user A by 200OK response, and PoC user A receives the indication that he can loquitur.
7.PoC server B sends to PoC customer end B by " invitation " request.Described invitation request comprises the request to autoanswer mode.
8. customer end B is accepted described request in the situation that not pointing out PoC user B.
9.PoC server B is forwarded to PoC server A by 200OK.
The mechanism that PoC standard definition arranges for the manual answer mode that allows calling party to surmount called subscriber's appointment.This relates to " MAO " parameter is included in the sip invite message of the startup PoC session being sent by calling party.When callee's terminal is received the invitation that comprises MAO parameter, this terminal automatically determines whether to allow calling subscriber's manual override.If so, automatically 200OK is replied and turn back to local PoC server, and the invitation that comprises MAO parameter is forwarded to called subscriber.If not, play ring warning, and and if work as called subscriber answer, response message only sent.
