Section 8.4.1 says:

          v=0
          o=Laura 289083124 289083124 IN IP4 seven.example.com
          c=IN IP4 192.0.2.1
          t=0 0
          a=group:FID 1 2
          m=audio 30000 RTP/AVP 0
          a=mid:1
          m=audio 20000 RTP/AVP 97
          c=IN IP4 192.0.2.2
          a=rtpmap:97 telephone-events
          a=mid:2

It should say:

          v=0
          o=Laura 289083124 289083124 IN IP4 seven.example.com
          c=IN IP4 192.0.2.1
          t=0 0
          a=group:FID 1 2
          m=audio 30000 RTP/AVP 0
          a=mid:1
          m=audio 20000 RTP/AVP 97
          c=IN IP4 192.0.2.2
          a=rtpmap:97 telephone-event
          a=mid:2

Notes:

Minor typo on page 10. Per RFC 4733, the rtpmap entry should use the media type "telephone-event" not "telephone-events".
