Early Media
Before a SIP call is established, the phone will play the early media (e.g., audio and video) to
the caller. Current implementation supports early media through the 183 message. When
the caller receives a 183 message with SDP before the call is established, a media channel is
established. This channel is used to provide the early media stream for the caller.
