             Summary: chan_sip: Asterisk creates ACK with empty Route: headers
                 Key: ASTERISK-23306
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23306
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: SVN
            Reporter: Matt Jordan
         Attachments: typescript.gz

When sending an ACK to a 200 OK, {{chan_sip}} is sending a Route: header unpopulated with any value. Hilarity ensues as the device continues to send the 200 OK to Asterisk.

Example from the attached log file for channel {{SIP/200-00000002}}:
