Information Services are services whereby information is provided in
response to user requests, and may include involvement of a human or
automated agent. A popular existing Information Service is Directory
Assistance (DA). Moving ahead, Information Services providers
envision exciting multimedia services that support simultaneous
voice and data interactions with full operator backup at any time
during the call. Information Services providers are planning to
migrate to SIP based platforms, which will enable such advanced
services, while continuing to support traditional DA services.

Operator Services are traditional PSTN services which often involve
providing human or automated assistance to a caller, and often
require the specialized capabilities traditionally provided by an
operator services switch. Market and/or regulatory factors in some
jurisdictions dictate that some subset of Operator Services continue
to be provided going forward.

This document aims to identify how Operator and Information Services
can be implemented using existing or currently proposed SIP
mechanisms, to identity existing protocol gaps, and to provide a set
of Best Current Practices to facilitate interoperability. For
Operator Services, the intention is to describe how current operator
services can continue to be provided to PSTN based subscribers via a
SIP based operator services architecture. It also looks at how
current operator services might be provided to SIP based subscribers
via such an architecture, but does not consider the larger question
of the need for or usefulness or suitability of each of these
services for SIP based subscribers.
