---------------------------------------

             Summary: Asterisk should inspect Min-SE header in an INVITE even if there is no Session-Expires present
                 Key: ASTERISK-20794
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20794
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: SVN, 1.8.19.0, 10.11.0, 11.1.0
            Reporter: Mark Michelson
            Severity: Minor


Consider the case that Asterisk is configured for "accept" mode for session timers. If a UAC sends an INVITE to Asterisk, it may have a Supported: timer header as well as a Min-SE header. If it includes a Min-SE header, we should inspect it and be sure not to send back a response with a Session-Expires header that is less than this Min-SE value.

Currently, Asterisk only inspects the Min-SE value if there is an accompanying Session-Expires header.
