[Dennis Haney (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=257287#comment-257287 ] 

Dennis Haney commented on ASTERISK-29760:
-----------------------------------------

Additionally, users in the field are reporting that sometimes they are able to hear when they are being overheard, with the sound of the overhearer coming through at very low volume even in the default mode. I.E. it has a very low volume whisper mode going on, even in the mode it should have whisper/barge at all.

> But can hear things just fine, so doesn't seem like a real problem.
> There are no log entries at any level of debugging that shows anything about barge mode (or any of the other modes) being engaged.
