[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=226547#comment-226547 ] 

Matt Jordan commented on ASTERISK-25163:
----------------------------------------

This actually is a deadlock in {{chan_sip}}, due to an inversion in locking between the Stasis MWI callback and the act of reloading.
