[Kevin Harwell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=247543#comment-247543 ] 

Kevin Harwell commented on ASTERISK-28473:
------------------------------------------

The session_media object is NULL, so when it tries to de-reference it it crashes. Either it was not properly setup to begin with or was "reset". Can you also post the log from around the time of an occurrence? I'm hoping it'll have an error and/or warning message in it regarding the mentioned negotiation failure.

> This is likely related to ASTERISK-27944... but we're seeing our favorite T38 negotiation crash again. Still looking for a scenario to reproduce cleanly, but this appears to happen in an odd T38 negotiation failure.
