ITU-T H.350 series defines a standard way to store/retrieve protocol
specific information for consumption by either UA or proxy.  Specific
protocols included in the series are H.323, H.320, and SIP.

SIP

	Is there a document that defines (or proposes) a standard way to
map protocol specific information into SIP to be consumed by a UA?
SIP-T provides  the entire SS7 packet embedded in the SIP message rather
than a translation of the fields.   I am hoping for a mapping like 
	
	redirection-number <==> redir-num: SIP header field 
	
	Is there such a document? 
	
	                                        Thanks for any info, 
	                                        Joe H.

	Everything is wonderful until you know something about it.
