[asterisk-bugs] [JIRA] (ASTERISK-29760) app_chanspy: Barge not supported when channel in a ConfBridge

[Joshua C. Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=257313#comment-257313 ] 

Joshua C. Colp commented on ASTERISK-29760:
-------------------------------------------

If you're doing it to a Local channel in the following scenario:

PJSIP/alice <-> Local/1;1, Local/1;2 <-> ConfBridge

Where barge is occurring on Local/1;1 or PJSIP/alice then it would work. But if it was activated on Local/1;2 it would not work.

> 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.
