Title : Updates to Asserted Identity in the Session Initiation Protocol (SIP)
Author(s) : J. Elwell
Filename : draft-ietf-sipping-update-pai-09.txt

SIP has a mechanism for conveying the asserted identity of the
originator of a request by means of the P-Asserted-Identity header
field. This header field is specified for use in requests using a
number of SIP methods, in particular the INVITE method. However, RFC
3325 does not specify the insertion of this header field by a trusted
UAC, does not specify the use of P-Asserted-Identity and P-Preferred-
Identity header fields with certain SIP methods such as UPDATE,
REGISTER, MESSAGE and PUBLISH, and does not specify how to handle an
unexpected number of URIs or unexpected URI schemes in these header
fields. This document extends RFC 3325 to cover these situations.
This work is being discussed on the sipping@xxxxxxxx mailing list.
