¿µ¹®³»¿ë¿ä¾à Early media refers to media (e.g., audio and video) that is exchanged before a particular session is accepted by the called user. The basic SIP specification (RFC 3261 [2]) only supports very simple early media mechanisms. These simple mechanisms have a number of problems related to forking and security. To solve these problems, this standard defines a new option-tag (early-session) and describes message flows.
