This object specifies whether Early Media
Cut Through is enabled or disabled for the
SIP response messages with status codes that
match cSipCfgEarlyMediaStatusCodeIndex.
If 'true', early media cut through is disabled,
and the user agent will process the message as
though it did not contain any SDP payload.
If 'false', early media cut through is enabled,
and the user agent will process the message
similar to a 183 (Session Progress) and cut
through for early media. The assumption being
that the SDP is an indication that the far end
is going to send early media.
