Hi Olle, AFAIK per title and the following snippet, he asked for Contact header parameter. I'm not positive what you are asking about (sip-uri header parameters, generic header conformance, or something else).
RFC 4485 discusses generic header conformance. RFC 3261 section 25.1 defines extension-header. RFC 3261 section 25.1 presents the ABNF for headers embedded within a sip-uri. > > I need to send a proprietary parameter in contact header > > in an INVITE message to other end. Something like this: > > > > Contact: "Sunil" > > <sip:48002@10.128.224.41;transport=tcp>;category:strvalue > -----Original Message----- > From: Olle E.
