Abstract
Early Media is the ability of two SIP user agents to communicate before a SIP call is actually established. Support for early media is important largely for interoperability with the PSTN. Unfortunately, many SIP devices are providing this capability today without a well- documented, consistent, and complete solution. We define the problem of early media, document and describe the difficulties with the current approach used in SIP UAs, and present a more formal protocol mechanism that resolves these difficulties
