Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a communication method and apparatus. Background technique [0002] Session Initial Protocol (English: Session Initial Protocol, SIP for short) is a control protocol of the application layer. SIP can be used to establish, modify and terminate multimedia sessions (or conferences). [0003] During the establishment of a SIP session (or conference), the SIP messages exchanged between the calling party and the called party (telephone or network device) usually include sensitive information of the sender. For example, the subject of the communication, the content of the communication, the location of the communication, and the call history information, and so on. According to the introduction of the RFC3261 standard, the calling party and the called party can use the Privacy header field to indicate whether to perform confidential processing on the above-ment...
