Currently, the following reasons are available:

•“BYE” means that the call was terminated by a regular BYE mes- sage.

•“No 200 Ok” is used when the call did not establish (4xx code or other final error codes).

•“OPTIONS” is used when the call was terminated because there was no response to an OPTIONS refresh request of the SBC.

•“media timeout” indicates that the call was terminated because the SBC detected that the media flows was disrupted.

•“one-way audio” is similar to media timeout, but happens when there was a longer period of one way audio.

•“Maximum Session Duration” is used when the SBC closes the call because the maximum duration (provided in the “expires” param- eter in the action=start result) has been reached.
