Early Media
Early media refers to media (e.g., audio and video) played to the caller before a SIP call is actually established.
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.
