Hi,
    in the following paragraph for the unicast IP
sessions :-
1. In section 4.1 it is mentioned for unicast sessions

"The semantics of this address and port depend on the
media and transport protocol defined.  By default,
this SHOULD be the remote address and remote port to
which data is sent."

    but how can the sender identify which port the
receiver is ready to ready to receive the data on.

2. also in section 5 it is mentioned that 

  " An SDP session description consists of a
session-level section followed by zero or more
media-level sections. "  
       this implies that the m= line is OPTIONAL.
      but then in the same section where the
differentiation of REQUIRED and OPTIONAL fields is
given 
Media description
         m=  (media name and transport address)
  m= does not contain the '*" field  which means it is
essential but this contradicts the earlier statement.
