We just submitted a new version of the miscellaneous-caps draft, with text that states that if the connection data capability attribute (a=ccap) is used the port number in the resulting SDP MUST be the same as in the original "m=" line, except for PSTN type bearers (when the port number used is 9).

A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the Multiparty Multimedia Session Control Working Group of the IETF.

	Title           : Miscellaneous Capabilities Negotiation in the Session Description Protocol (SDP)
	Author(s)       : Miguel A. Garcia-Martin
                          Simo Veikkolainen

   SDP has been extended with a capability negotiation mechanism
   framework that allows the endpoints to negotiate transport protocols
   and attributes.  This framework has been extended with a media
   capabilities negotiation mechanism that allows endpoints to negotiate
   additional media-related capabilities.  This negotiation is embedded
   into the widely-used SDP offer/answer procedures.

   This memo extends the SDP capability negotiation framework to allow
   endpoints to negotiate three additional SDP capabilities.  In
   particular, this memo provides a mechanism to negotiate bandwidth
   ('b=' line), connection data ('c=' line), and titles ('i=' line for
   each session or media).
