This document defines the private SIP extension header
P-Access-Network-Info. This mechanism is useful in SIP networks that
are partitioned, such as 3G wireless networks which are partitioned at
the SIP layer into 'access' and 'home' networks. SIP User Agents may
use this header to relay information about the access network to
serving proxies in their home network. The serving proxy may then use
this information to optimize services for the UA. For example, a 3GPP
terminal uses this header to pass information about the access network
such as radio access technology and cell ID to its home service.

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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
