Configuring Early Media Session
This section describes the method of handling 18x provisional response.
Ubigate iBG2016 can receive the Answer SDP for Offer SDP delivered being
included in INVITE, via 180 or 183 provisional response message. If this SDP
is processed, a media path is opened prior to Answer status. Using the disable-
early-media command in a SIP-UA configuration mode, you can control the
method for Ubigate iBG2016 to handle the SDP delivered via 180 response.
To the contrary, it is possible to control whether, when Ubigate iBG2016 sends
a 18x provisional response including SDP, to send 180 or 183 response, or
send it together with SDP, by using the alert-cut-through command.
How to Configure 180 Provisional Response Handling
You can set the method of handling 180 provisional response where SDP is
included, in the following way.
