   Directory Assistance (DA) is a well known service in today's PSTN,

   and is generally identified with "411" or "NPA-555-1212" type

   services in North America.  Today's DA services are already becoming

   more advanced.  Currently the DA service can complete the call for

   the user, can send SMS with the listing to the user's wireless phone,

   and can provide the user with a wide range of information, such as

   movie listings and the weather.

   Moving ahead, DA providers envision exciting multimedia services that

   support simultaneous voice and data interactions with full operator

   backup at any time during the call.  For instance, a DA directions

   service may announce and display directions to the requested listing,

   with the option for the caller to request transfer to an operator

   with the latest call context information.

   DA providers are planning to migrate to SIP based platforms, which

   will enable such advanced services, while continuing to support

   traditional DA services.

   Implementing DA services with SIP will require the exchange of

   certain information which is not normally exchanged for other types

   of calls.  This document aims to identify such information, and

   stimulate discussion about how this information could be exchanged.

   Should it be decided that extensions to SIP are required, it is the

   authors' intention to use the SIP change process documented in [BCP

   67] to attain standardization.

Send a message to:

In the body type:

        "FILE /internet-drafts/draft-haluska-sipping-directory-assistance-00.txt".

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.
