             Summary: PJSIP Transfers Broken with Compact Headers Enabled
                 Key: ASTERISK-26655
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26655
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 14.2.1
            Reporter: JoshE


With compact headers enabled on all Asterisk 14 versions, a SIP REFER is broken - returns a 400 error.  Turning compact headers off causes transfers to happen normally.

Here are the relevant messages:
