  "abstract": "This specification defines the new UPDATE method for the Session\r\nInitiation Protocol (SIP). UPDATE allows a client to update\r\nparameters of a session (such as the set of media streams and their\r\ncodecs) but has no impact on the state of a dialog. In that sense, it\r\nis like a re-INVITE, but can be sent before the initial INVITE has\r\ncompleted. This makes it very useful for updating session parameters\r\nwithin early dialogs.\r\n\r\n",
