             Summary: pjsip: 183 without To tag does not negotiate media
                 Key: ASTERISK-27442
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27442
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
            Reporter: Kevin Harwell
            Severity: Minor


If a 183 with sdp response is receive without a To tag the sdp is not negotiated.

According to RFC 3261 section 12.1.2 while a To tag is required, the client needs to still be able to handle the missing tag case for backwards compatibility.
