Title : Experiments on SPIT in the Commercial VoIP Services
Author(s) : J. Choi, et al.
Filename : draft-choi-sipping-experiments-spit-01.txt

This document shows some experimental results on SPIT on commercial
VoIP services, in which a SIP UA has not been secured by SIP security
protocol such as TLS. Although many service providers have been
applying the HTTP digest scheme to authenticate a SIP UA, they often
do not apply SIP signaling protection against potential threats
between the SIP UA and the SIP proxy. This cause vulnerabilities to
the VoIP services like SPIT. The aim of this memo is to inform the
service providers of SPIT threats by showing some experimental
results of SPIT on current VoIP networks.

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.
