c= must be: 1. in the session description and in none, some or all of the media descriptions
--OR--- 2. NOT in the session description and in ALL the media descriptions Regards, Attila -----Original Message----- From: [EMAIL PROTECTED] on behalf of Yong Xin Sent: Fri 23/02/2007 18:21 To: [email protected] Cc: Subject: [Sip-implementors] RFC 2327 SDP "c=" line question Hi, We have different interpretation regarding to the "c=" line definition in RFC 2327. Session description c=* (connection information - not required if included in all media) Media description c=* (connection information - optional if included at session-level) I think "c=" line is optional when SDP has no "m=" line, since I don't see a use case to present connection info when there's no media description. But some people think the above definition indicates the "c=" line is mandatory and must be present in either session or media level in any case. Could anyone tell me which interpretation is correct?
