<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Out of curiosity, is this crash occurring just because the "underlying channel" is NULL in this function? If so we should be able to detect that and exit from this function without trying to play a file to a non existent channel.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Actually, I think underlying_channel is a dangling pointer to a nulled out channel. The actual segfault occurs when dereferencing a null tech in ast_channel_setoption.</pre>

We just need to make sure that channel and the channel driver can not go out from underneath us on shutdown until we are done with them. Modules can be ref counted if that is the source of the issue.</pre>

This patch prevents ConfBridge from playing any additional sounds if Asterisk is shutting down.</pre>
