Thanks attila, Where can i find more specifics of it being an error
mentioned.. i mean is it in any of the RFC.

RFC 4566(SDP) mentions

*"In general, the "o=" field serves as a globally unique identifier for
   this version of this session description, and the subfields excepting
   the version taken together identify the session irrespective of any
   modifications."
*


I was jez wondering if connection field can still exist without an IP
Address, as the Origin field is *mandatory *and serves as a global
identifier for the session. though i cant really think of a Use case
currently :(.......

br,
Vish
