If enabled, the gateway sends 183 Session
Progress response with SDP (instead of
180 Ringing), allowing the media stream to
be set up prior to the answering of the call.
Note: Sending 183 response depends on the
Progress Indicator. It is sent only if PI=1 or
PI=8 was received in Proceeding or Alert PRI
messages. For CAS gateways see the
ProgressIndicator2IP parameter.
