Section 8 says:

The port number of every "m=" line MUST be set to zero, but the connection address is arbitrary.

The desired status line corresponding to the precondition that
triggered the failure MUST use the "failure" strength-tag, as shown
in the example below:

      m=audio 20000 RTP/AVP 0
      a=des:qos failure e2e send

It should say:

The port number of every "m=" line MUST be set to zero, but the connection address is arbitrary.

The desired status line corresponding to the precondition that
triggered the failure MUST use the "failure" strength-tag, as shown
in the example below:

      m=audio 0 RTP/AVP 0
      a=des:qos failure e2e send

Notes:

The G711U codec's payload type 0 that appears in the m-line, probably led to the typo error with the incorrect port number (20000 instead of 0).
