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.
180 Ring Workaround
180 ring workaround defines whether to deal with the 180 message received after the 183
message. When the caller receives a 183 message, it suppresses any local ringback tone and
begins to play the media received. 180 ring workaround allows Skype for Business phones to
resume and play the local ringback tone upon a subsequent 180 message received.
Procedure
180 ring workaround can be configured using the configuration files or locally.
