The present invention discloses a SIP message processing method and device, which are used to solve the problem of low SIP message processing efficiency caused by limited device processing performance. This scheme includes: receiving a first SIP message sent by an IMS core network; forwarding the first SIP message to a corresponding SIP business processing device through a service network side address port of a SIP entity corresponding to the first SIP message; if a second SIP message sent by the SIP business processing device is received, the second SIP message is sent to the IMS core network through a CSCF side port of a target SIP entity that receives the second SIP message. Since the service network side address port of the SIP entity corresponds to an intranet service port of a unique SIP business processing device, it is not necessary to parse the SIP message sent by the IMS core network and can efficiently forward it to the corresponding SIP business processing device. For the SIP message sent by the SIP business processing device, it can be quickly forwarded according to the CSCF side address port, thereby reducing the processing performance consumed by the SIP access device in parsing the SIP message.
