[asterisk-bugs] [JIRA] (ASTERISK-28010) PJSIP: Crash with MWI implicit subscription replaced by explicit

[Sean Bright (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-28010?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Bright updated ASTERISK-28010:
-----------------------------------

    Description: 
It looks like there's an issue with MWI subscriptions and the topic somehow ends up NULL. This could be due to implicit subscriptions changing to explicit. There could be a race condition when things are being set up and the call is hung up almost immediately.
