And step two, the VOIP-UP user takes off the phone and reports an off-hook event to the VOIP-CP.
And thirdly, after receiving the off-hook event, the SIP service module applies for establishing VOIP channel resources to the VOIP-UP to complete the establishment of the bidirectional VOIP channel, and then informs the SIP protocol module of completing the establishment of the SIP session.
