Subject: SG11-Liaison - translations

From: [email-masked] (Lawrence Conroy)
Date: Wed, 24 Mar 1999 12:50:18 +0000

Hi All,
   for those of you (me included !) who can't read text/enriched, here's
my transliteration of the Liaison statement from SG11 in plain text, and
a stab at HTML.

As I have the honour?! of being one of the authors of the PINT draft, and I
put in (then took out, then re-inserted) the text in question, I'll try to
put together some notes in response.

The following correspondence from ITU-T SG 11 to the participants of the
PINT WG of the IETF:

During its March 1999 meeting, ITU-T SG11 participants reviewed with
keen interest the most recent results of the PINT working group of the
IETF. In addition to those who are concerned mostly with functional
architectures (Q5/11) and who have historically been the main source of
interaction with PINT, this review involved experts in many other
aspects of communications. In particular, those responsible for ISDN
signaling would like to share an observation that may have impact on the
utility of the PINT specification in certain public network
environments.

It is the understanding of these reviewers that it may be possible for
the "calling user" to initiate a phone call anonymously from an IP phone
service. From an ISDN perspective it would be preferable that a calling
line number (E.164-based) is always passed to the network with a
"restricted" indicator to provide for a number of situations involving
an anonymous call. "Calling Line Identification" (CLI) is not just used
for the presentation type services that have been accommodated in the
latest PINT draft specification. A few of the other service types that
take advantage of CLI are listed below.

* Support of emergency services

A caller may not always be in a position to give the emergency operator
the real location of the emergency. In this case the "CLI" is used to
determine the location and dispatch the Police, Fire Brigade or
Ambulance.

* Malicious Call ID

Unfortunately, not all calls are made with the best of intentions to
either individuals, in the form of harassment, or to companies, e.g. a
plumber sending a rival plumber to fictitious jobs.

* Network Management

Telephone companies require this information so that the network can be
properly managed for maintenance, dimensioning, and billing purposes.

It is hoped that this information is of use in the PINT studies. If
additional information is desired, then please do not hesitate to ask.
