[Sip] [sip] extensions of "handling" parameter of Content-Disposition header
Hello,
can anyone please
give me an expert opinion on possible extensions of "handling" parameter defined
in RFC3204/RFC3459?
Is it appropriate to extend and use
the "handling" parameter of Content-Disposition header of a MIME
body inserted in a SIP request to
signal a particular action which the
sender requests from the recipient?
For example - if the "handling" parameter contained value "XYZ",
the SIP request recipient would do a special action ActionXYZ using the MIME body. If the MIME body was included in the SIP request without
the "handling" parameter, the recipient would NOT do the special action
XYZ and instead would just store or render
the MIME body.
AFAIK,
RFC3204 defines parameter "handling" of Content-Disposition header of a
MIME body with two defined parameter values "required" and "optional" and allows for possible future extensions. RFC3204
also states "The handling parameter, handling-parm, describes how the UAS should
react if it receives a message body whose content type or disposition type it
does not understand". RFC3459 says "The
protocol described here is identical in functionality to RFC 3204 with respect
to SIP.".
Kind
