[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=211423#comment-211423 ] 

Matt Jordan commented on ASTERISK-22802:
----------------------------------------

It appears as if somehow {{conf->chan}} is NULL when it enters into a {{while}} loop that calls {{ast_check_hangup}} repeatedly. In general, I would have expected that {{conf->chan}} is non-NULL at that point, particularly if the system has been configured correctly with DAHDI.
