<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There's no sense in returning a failure result if things that use this method aren't going to check it.
Since a failure to stop MOH isn't a reason to cancel most subsequent actions, I'd change this method to return a void. You should probably instead log a WARNING if the user cannot be suspended from the bridge.</pre>

2. I'm not sure why nonwaiting_participants would be >= 2 here. If there are any participants that are not marked users, and no marked users exist, we probably need to start MOH on them.
3. A number of comments in this block serve no purpose in clarifying the intent of the code, e.g., "All conditions needed to enable speech are satisfied"</pre>
