Title : End-to-End VoIP Header Compression Using cRTP

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.

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.
