Section 4.2 says:

m=audio 59000 UDP/TLS/RTP/AVP 98

It should say:

m=audio 59000 UDP/TLS/RTP/SAVP 98

Notes:

The example missed an S in the mine type. The list of allowed types is at https://www.iana.org/assignments/sdp-parameters/sdp-parameters.xhtml#sdp-parameters-2 and UDP/TLS/RTP/AVP is not a registered device. Because this is over TLS, it is a SRTP (not RTP) and should use SAVP not AVP.
