[asterisk-bugs] [JIRA] Commented: (ASTERISK-20550) Deadlock between SIP pvts being placed in container and CLI command 'sip show channels'

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=198264#comment-198264 ] 

Matt Jordan commented on ASTERISK-20550:
----------------------------------------

'sip show peer' won't, because it doesn't have to interact with the dialogs.

As much as I'd like to say I have a patch in hand, I don't - was merely providing analysis based on your backtraces to help whoever tackles this issue.
