Title : Proposed Clarification of Encoding of Telephone
Numbers in SIP URis
Author(s) : R. Mahy

There is much confusion about how to represent telephone numbers and
other related strings of digits in SIP URIs and tel: URIs, especailly
when those digit strings are of purely local significance. This
matter is complicated by the underspecification of the 'user' SIP URI
parameter in RFC3261 and the phone-context parameter in RFC2806.This
document proposes specific semantics for the user=phone parameter and
describes several ways to encode digits strings and phone numbers in
a manner consistent with that proposal.

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
Internet-Draft.
