In section 5.7 we have:
5.7. Connection Data ("c=")
c=<nettype> <addrtype> <connection-address>
each of the components between the brackets is mandatory
"c=IN IP4 " is not allowed but "c=IN IP4 0.0.0.0" would be ok.

Attila

differentscenarios of connection field.
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 :(.......

Hi all,
Can a SDP content have a Connection field without an IP
address.... to
be more precise...
Case 1: "c=IN IP4 192.168.1.2 " (Normal scenarion) Case 2: "c=IN
IP4 "
(No I P address is mentioned)
Shud an SDP Parser Raise an Error on Case 2 or shud it parse the
Message
and pass on to stack as an Valid SDP Content.
Please correct me if there'z any info i have wrongly
interpreted....
best regards,
Vishwas
