VoIP typically uses the encapsulation voice/RTP/UDP/IP, wherein the 
packet header is at least 40 bytes, while the voice payload is typically 
no more than 30 bytes.  VoIP header compression can significantly reduce 
the VoIP overhead through various compression mechanisms.  This is 
important on access links where bandwidth is scarce, and can be 
important on backbone facilities, especially where costs are high (e.g., 
some global cross-sections).  In this draft we propose to re-use the 
methods in cRTP to determine the header compression context and to use 
the cRTP session context ID to route a compressed packet between the 
ingress and egress routers.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
